Correct Option: A

The first secretary of Indian National Congress was Allan Octavian Hume. The Congress was founded by Indian and British members of the Theosophical Society movement, most notably A.O. Hume. It has been suggested that the idea was originally conceived in a private meeting of seventeen men after a Theosophical Convention held at Madras in December 1884. Hume took the initiative, and it was in March 1885 that the first notice was issued convening the first Indian National Union to meet at Poona the following December.
