Which Governor General introduced the policy of Subsidiary alliance in India?

Lord Wellesley

The correct answer is Option 2-  Lord Wellesley

The policy of Subsidiary Alliance in India was introduced by Lord Wellesley. He was the Governor-General of India from 1798 to 1805.

The Subsidiary Alliance was a system of treaties between the British East India Company and the Indian princely states. Under the terms of the treaty, the princely states were required to disband their own armies and accept a British force stationed in their territory. The princely states were also required to pay for the maintenance of the British force.

The Subsidiary Alliance was a controversial policy, but it was effective in establishing British hegemony in India. It also allowed the British to interfere in the internal affairs of the princely states.
