The correct answer is (d) he wanted to train British civilians for administrative purposes in India.
Lord Wellesley, the Governor-General of India from 1798 to 1805, established the Fort William College in Calcutta in 1800. The college was established with the aim of training the newly appointed civil servants in the administrative and legal systems of India, as well as to improve their proficiency in Indian languages. The college also served as a center for research in Indian languages, literature, and culture. The establishment of the Fort William College was part of Wellesley`s broader policy of making the East India Company`s administration in India more efficient and effective.
