- The British East India Company, initially a trading entity, gradually established its control over Indian territories through various means. This policy was implemented by Lord Dalhousie, leading to widespread resentment among Indian rulers.
Assertion (A): The Doctrine of Lapse was implemented to expand British territories.
Reason (R): It allowed the British to annex states with no direct male heir.
Choose the correct option:
(A) (A) is true but (R) is false
(B) (A) is false but (R) is true
(C) Both (A) and (R) are true but (R) is not the correct explanation of (A)
(D) Both (A) and (R) are true and (R) is the correct explanation of (A)
Answer: d
Explanation:
- Assertion (A) is true: The Doctrine of Lapse was an annexation policy implemented by Lord Dalhousie (Governor-General from 1848 to 1856) with the primary goal of expanding British territorial control in India.
- Reason (R) is true: The mechanism of this policy was that any princely state under British influence would automatically “lapse” into British hands if the ruler died without a natural male heir. It specifically disregarded the traditional Indian practice of adoption for succession.
- (R) explains (A): The reason (R) directly explains how the policy in (A) achieved its goal of expansion. By creating a legal pretext to take over states without biological male heirs, the British were able to systematically annex territories like Satara, Jhansi, and Nagpur.

- With reference to the Guhilots/Sisodiyas, Rathors and Kachwahas, consider the following statements:
The Guhilots ruled over Mewar with Chittor as their capital.
Sawai Jai Singh of the Rathor dynasty was a high-ranking noble under the Mughals.
Mansingh of the Kachwahas was a trusted commander of Akbar.
Maharana Pratap of the Sisodiyas fought against Akbar at the Battle of Haldighati.
Jaswant Singh of the Kachwahas was also an astronomer.

(A) 1, 3 and 4 only
(B) 1, 3, 4 and 5 only
(C) 2, 3 and 4 only
(D) 1, 2, 3 and 5 only
Answer: a
Explanation:
- The Guhilots ruled over Mewar with Chittor as their capital.
- The Guhilot dynasty (and later their Sisodiya branch) established the Kingdom of Mewar. Chittor served as their historic capital before the capital shifted to Udaipur.
- Sawai Jai Singh of the Rathor dynasty was a high-ranking noble under the Mughals.
- This is incorrect because Sawai Jai Singh II belonged to the Kachwaha dynasty of Amber (Jaipur), not the Rathor dynasty. The Rathors primarily ruled Marwar (Jodhpur).
- Mansingh of the Kachwahas was a trusted commander of Akbar.
- Raja Man Singh I of Amber (Kachwaha dynasty) was one of Emperor Akbar’s most prominent and trusted generals (“Navratnas”). He led the Mughal forces in major campaigns, including the Battle of Haldighati.
- Maharana Pratap of the Sisodiyas fought against Akbar at the Battle of Haldighati.
- Maharana Pratap, the Sisodiya ruler of Mewar, famously resisted Mughal expansion and fought Akbar’s forces (led by Man Singh) at Haldighati in 1576.
- Jaswant Singh of the Kachwahas was also an astronomer.
- This is incorrect due to a mix-up of names. While Sawai Jai Singh II (Kachwaha) was the famous astronomer who built the Jantar Mantar observatories, Jaswant Singh was a famous ruler of the Rathor dynasty of Marwar.
- In 1917, Mahatma Gandhi led a movement, which marked his first major involvement in the Indian independence movement. This movement was aimed at addressing the grievances of indigo planters suffering under oppressive policies.
Assertion (A): The Champaran Satyagraha was Gandhi’s first major mass movement in India.
Reason (R): The movement aimed at resolving the issues faced by the indigo planters.
Choose the correct option:
(A) Both (A) and (R) are true and (R) is the correct explanation of (A)
(B) (A) is false but (R) is true
(C) Both (A) and (R) are true but (R) is not the correct explanation of (A)
(D) (A) is true but (R) is false
Answer: a
Explanation:
- Assertion (A) is true: The Champaran Satyagraha of 1917 was indeed Mahatma Gandhi’s first major civil disobedience movement in India after his return from South Africa. It marked the beginning of his influential role in the Indian freedom struggle.
- Reason (R) is true: The core purpose of the movement was to protest the Tinkathia system, where British planters forced local farmers to grow indigo on 3/20th of their land under highly exploitative conditions.
- Connection: Because Gandhi successfully organized and led this specific struggle for the indigo planters (R), it became his first “Satyagraha” or mass movement on Indian soil (A).
- Match the following lenses/mirrors with their correct applications.
Column – I (Lenses/Mirrors) | Column – II (Application) i. Concave mirror | p. Used in cameras and projectors for focusing light ii. Convex mirror | q. Used in correcting myopia (short-sightedness) iii. Convex lens | r. Used in vehicles for rear-viewing iv. Concave lens | s. Used in shaving to produce magnified upright image
Select the correct matching option:
| i | ii | iii | iv | |
| (A) | s | r | q | p |
| (B) | r | s | q | p |
| (C) | s | r | p | q |
| (D) | r | s | p | q |
Answer: c
Explanation:
- i. Concave mirror → s. Used in shaving to produce magnified upright image: When an object is placed close to a concave mirror, it creates a virtual, erect, and enlarged image, making it ideal for seeing fine details while shaving.
- ii. Convex mirror → r. Used in vehicles for rear-viewing: These mirrors always form a diminished, upright image and have a wider field of view, allowing drivers to see a larger area of the traffic behind them.
- iii. Convex lens → p. Used in cameras and projectors for focusing light: Because it is a converging lens, it is used in optical instruments like cameras and projectors to focus light and form clear images on a sensor or screen.
- iv. Concave lens → q. Used in correcting myopia (short-sightedness): These are diverging lenses used in spectacles to help spread incoming light so that it focuses correctly on the retina for those who cannot see distant objects clearly

- Which of the following best explains the pressure flow hypothesis in phloem transport?
(A) Movement of water only through xylem
(B) Transport depends only on gravity
(C) Osmotic pressure difference between source and sink
(D) Active transport of sugars from sink to source
Answer: c
Explanation:
The pressure flow hypothesis (also called mass flow hypothesis) explains how food (mainly sugars like sucrose) is transported in plants through the phloem:
- At the source (e.g., leaves), sugars are actively loaded into the phloem.
- This increases the osmotic pressure, causing water to enter from the xylem.
- The resulting high pressure pushes the sap toward the sink (e.g., roots, fruits).
- At the sink, sugars are unloaded, lowering osmotic pressure.

(A) 2 and 4 only
(B) 1, 2 and 4 only
(C) 3 and 4 only
(D) 1 and 2 only
Answer: b
Explanation:
- Durlabhavardhana, also known as Prajnaditya, was the founder of the dynasty.
- Durlabhavardhana founded the Karkota dynasty in the 7th century (c. 625 CE). He was the son-in-law of Baladitya, the last king of the Gonanda dynasty. He is also referred to by the title Prajnaditya in historical texts.
- Lalitaditya Muktapida defeated the Turks and built the Martand Sun Temple at Anantnag.
- Lalitaditya Muktapida (r. 724–760 CE) is the most famous ruler of this dynasty. He is credited with defeating various foreign invaders, including the Turks, Arabs, and Tibetans.
- He built the colossal Martand Sun Temple near Anantnag, which is a masterpiece of Kashmiri architecture.
- Vajraditya’s reign was marked by territorial expansion into the Deccan.
- Vajraditya (also known as Bappiyaka) was a successor of Lalitaditya, but his reign was marked by decline and cruelty rather than expansion. Most historians agree that the Karkota expansion reached its zenith under Lalitaditya; subsequent rulers like Vajraditya presided over a weakening state.
- Jayapida imposed excessive taxation, which weakened his rule.
- Jayapida Vinayaditya, the grandson of Lalitaditya, initially attempted to emulate his grandfather’s conquests. However, according to Kalhana’s Rajatarangini, his later years were marked by tyrannical rule and excessive taxation (including taxing the Brahmins), which led to widespread resentment and weakened the dynasty’s stability.

- A particle is found to be at rest when observed from a reference frame S₁ and the same particle is found to move with a constant velocity when observed from another frame S₂. Which of the following statements is true?
(A) Both S₁ and S₂ are inertial frames.
(B) Both S₁ and S₂ are non-inertial frames.
(C) S₂ is an inertial frame but S₁ is a non-inertial frame.
(D) S₁ is an inertial frame but S₂ is a non-inertial frame.
Answer: (A)
Explanation:
In inertial frames, a free particle either remains at rest or moves with constant velocity (Newton’s First Law).
- In S₁: velocity = 0 (at rest) → inertial.
- In S₂: constant non-zero velocity → inertial.
Both frames are inertial; they are simply in relative motion with constant velocity with respect to each other. If any frame had acceleration, the particle would appear to have acceleration.

(A) 2v₁v₂ / (v₁ + v₂)
(B) (v₁² + v₂²) / (v₁ + v₂)
(C) √(v₁v₂)
(D) (v₁ + v₂) / 2
Answer: (A) 2v₁v₂ / (v₁ + v₂)
Explanation:
When equal distances (x each) are covered at different constant velocities, average velocity is given by the harmonic mean:
Total distance = 2x
Total time = (x/v₁) + (x/v₂)
Average velocity = 2x / [x(v₁ + v₂)/(v₁v₂)] = 2v₁v₂ / (v₁ + v₂)
(Note: Arithmetic mean (v₁ + v₂)/2 is used only when equal times are taken.)
- Temporary parasites are
(A) Free living but become parasitic if opportunity arises
(B) Completes its life cycle inside the host

Whakaari, the partially submerged active volcano located 48 kilometers off the coast of New Zealand’s North Island in the Bay of Plenty, is more commonly known as White Island
- With reference to the White Mutiny, consider the following statements.
- It posed a serious threat to British control in India, similar to the Revolt of 1857.
- It was primarily caused by the grievances of Indian sepoys who felt mistreated by British officers.
Which of the statements given above is/are correct?
(A) Both 1 and 2
(B) Neither 1 nor 2
(C) 2 only
(D) 1 only
Statement 1 is incorrect: The White Mutiny (1859–61) was a rebellion by European (white) soldiers of the East India Company’s army who were unhappy about being transferred to the service of the British Crown after the Company was dissolved. While it caused significant military unrest and had to be resolved through offers of discharge or bounties, it did not pose a serious threat to British control over India comparable to the Revolt of 1857, which was a widespread uprising involving Indian sepoys, peasants, and rulers.
Statement 2 is incorrect: The grievances were not those of Indian sepoys. The mutiny was exclusively about the service conditions and perceived loss of status of European troops. The Indian sepoys had already rebelled in 1857 (the Revolt of 1857), and it was that rebellion which led to the dissolution of the East India Company and the subsequent White Mutiny.
Since both statements contain factual errors, the answer is (B) Neither 1 nor 2.
- Given below are two statements, one is labelled as Assertion (A) and other is labelled as Reason (R). In light of the below given statements choose the most appropriate answer from the options.
Assertion (A): Transpiration helps in the ascent of sap.
Reason (R): Transpiration increases osmotic pressure in roots.
(A) (A) is true but (R) is false
(B) (A) is false but (R) is true
(C) Both (A) and (R) are true but (R) is not the correct explanation of (A)
(D) Both (A) and (R) are true and (R) is the correct explanation of (A)
Explanation:
- Assertion (A): Transpiration helps in the ascent of sap
- Transpiration creates a transpirational pull (negative pressure) in the xylem, which helps water move upward from roots to leaves.
- Reason (R): Transpiration increases osmotic pressure in roots
- Osmotic pressure in roots is mainly due to active absorption of minerals and water, not directly due to transpiration.
- Transpiration primarily affects the pull from leaves, not osmotic pressure in roots
- What is the correct order of stages in incomplete metamorphosis in insects?
(A) Egg – Nymph – Adult
(B) Egg – Nymph – Pupa – Adult
(C) Egg – Larva – Adult
(D) Egg – Larva – Pupa – Adult
The life cycle has three stages:
- Egg
- Nymph (resembles a small adult but immature)
- Adult
- There is no pupal stage.
Examples include insects like grasshoppers, cockroaches, and dragonflies.
- Barium appears primarily in ore(s) of
(A) Both barite and witherite
(B) Barite only
(C) Witherite only
(D) None of the above
The correct answer is (A) Both barite and witherite.
Barium is a reactive alkaline earth metal that does not occur naturally in its elemental form. Its primary commercial and geological sources are these two specific mineral ores:
- Barite (Baryte): Composed of Barium Sulfate (BaSO₄). This is the most abundant and economically important barium mineral, widely used in drilling fluids (drilling mud) for oil and gas wells.
- Witherite: Composed of Barium Carbonate (BaCO₃). While less common than barite, it is a significant secondary ore of barium and has been historically important for producing barium chemicals
- Given below are two statements. One is labelled as Assertion (A) and other is labelled as Reason (R).
Assertion (A): Bihar is a backward State of the Country.
Reason (R): It is characterized by regional disparities in the level of development.
Select the correct answer from the orders given below:
(A) (A) is true but (R) is false
(B) (A) is false but (R) is true
(C) Both (A) and (R) are correct and (R) is the correct explanation of (A)
(D) Both (A) and (R) are correct and (R) is not the correct explanation of (A)
The correct answer is (D) Both (A) and (R) are correct and (R) is not the correct explanation of (A).
- Assertion (A) is true: Bihar consistently ranks at the bottom among Indian states in terms of per capita income, industrialization, and Human Development Index (HDI). It is widely classified as a socio-economically backward state.
- Reason (R) is true: Bihar does exhibit significant regional disparities. For example, there is a notable development gap between the relatively more developed districts of South/Central Bihar and the flood-prone, less developed districts of North Bihar (such as the Kosi-Seemanchal region).
- Consider the following statements regarding the Satyashodhak Samaj.
- It was primarily aimed at challenging the Brahminical dominance and promoting equality for lower castes.
- It worked towards universal education for women and lower castes.
- The Samaj promoted the idea of untouchability as a necessary social custom.
How many of the statements given above is/are correct?
(A) All three
(B) None of these
(C) Only two
(D) Only one
The correct answer is (C) Only two.
Here is the analysis of the three statements regarding the Satyashodhak Samaj, founded by Jyotirao Phule in 1873:
- Statement 1 is correct: The primary aim of the Satyashodhak Samaj (Society of Seekers of Truth) was to challenge Brahminical dominance and the caste system. It sought to liberate the Shudras, Dalits (Ati-Shudras), and other lower castes from social and religious exploitation.
- Statement 2 is correct: The Samaj placed a strong emphasis on social reform through education. Jyotirao Phule and his wife Savitribai Phule were pioneers in opening schools for girls and lower-caste children, working actively toward universal education for women and the oppressed classes.
- Statement 3 is incorrect: The Satyashodhak Samaj was fundamentally opposed to untouchability. It fought against the practice of untouchability and the entire hierarchical structure of the caste system; it did not promote it as a necessary custom.
Since statements 1 and 2 are correct and statement 3 is incorrect, only two statements are correct

- Consider the interaction forces between two protons separated by a distance of the order of 1 femtometer (10⁻¹⁵ m). The correct order of the strengths of the electromagnetic, gravitational and nuclear forces acting between them is
(A) Nuclear > Electromagnetic > Gravitational
(B) Nuclear > Gravitational > Electromagnetic
(C) Electromagnetic > Nuclear > Gravitational
(D) Gravitational > Electromagnetic > Nuclear
The correct answer is (A) Nuclear > Electromagnetic > Gravitational.
At a distance of 1 femtometer (10⁻¹⁵ m)—the typical range of the strong nuclear force within an atomic nucleus—the relative strengths of the forces between two protons are approximately:
- Strong Nuclear Force: ~1 (Strongest at this short range; it overcomes the electromagnetic repulsion to bind protons together in the nucleus.)
- Electromagnetic Force: ~10⁻² (The repulsive force between two positively charged protons is significant but about 100 times weaker than the strong force.)
- Gravitational Force: ~10⁻³⁸ (The mass of a proton is so tiny that gravity is negligible at the subatomic level.)
Thus, the order is Nuclear > Electromagnetic > Gravitational.
