Who wrote to the Committee of Public Instruction on introducing English as official language of the Government and that of education?

Explanation

As Governor-General (1828–35), Lord William Bentinck directed the General Committee of Public Instruction towards English. His Resolution of 7 March 1835, issued after Macaulay's Minute, made English the medium of higher education; English replaced Persian in courts and administration from 1837. Clive and Hastings predate the debate, and Zachary Macaulay was T. B. Macaulay's father, an abolitionist in England.

Note: Accepted key. Bentinck acted on Macaulay's Minute; the question's wording simplifies the history.
