The correct option is B Marquis Dupleix
In 1742, Dupleix was appointed governor general of the company with authority over French investments in India. He sent an expedition against Fort St. David in 1747, but it was defeated by the Nawab of Arcot, who was allied with the British. In the end, Dupleix was unable to match the British aspirations and activities directed by Robert Clive, and French influence declined as British power increased.
