The correct answer is C. Lord Dalhousie.
The Doctrine of Lapse was a British policy in India, enacted under the administration of Lord Dalhousie as Governor-General from 1848 to 1856, as a way to expand the British Empire. The doctrine stated that if a princely Indian state fell under “lapse”, that is, if the ruler died without a male heir, the state would be annexed by the British East India Company.
The doctrine was controversial, and was opposed by many Indian nationalists. It was also one of the factors that led to the Indian Rebellion of 1857.
