Which of the following were important changes that were introduced by the British after the revolt of 1857?

(A) The British Government accepted direct responsibility for ruling India.

(B) It was decided that all the territories of Indian rulers would be annexed immediately.

(C) The proportion of Indian soldiers in the army would be reduced and European soldiers would be increased.

(D) It was to protect landlords and zamindars and give them security of rights over their lands.

Choose the correct answer from the options given below:

(A) The British Government accepted direct responsibility for ruling India -> The Government of India Act 1858 transferred power from the East India Company to the British Crown, marking direct British governance.

(B) It was decided that all the territories of Indian rulers would be annexed immediately -> The British actually REVERSED their aggressive annexation policy (like Doctrine of Lapse) and promised to respect princely states' rights through Queen Victoria's Proclamation of 1858.

(C) The proportion of Indian soldiers in the army would be reduced and European soldiers would be increased -> The British recognized the danger of having too many Indian soldiers, so they increased European troops and changed recruitment patterns.

(D) It was to protect landlords and zamindars and give them security of rights over their lands -> The British sought to create a loyal conservative class by securing landlords' and zamindars' property rights.

Hence, Option 2: (A), (C) and (D) Only -> Statement (B) is incorrect as the British abandoned aggressive annexation policies after 1857 and instead adopted a policy of non-interference with princely states. The other three statements accurately reflect the major administrative, military, and social reforms implemented post-1857 Revolt -> correct
