In July 1942, the Congress Working Committee met at Wardha and resolved that it would authorise Gandhi to take charge of the non-violent mass movement. The resolution generally referred to as the ‘Quit India’ resolution. Proposed by Jawaharlal Nehru and seconded by Sardar Patel, it was to be approved by the All India Congress Committee meeting in Bombay in August. The Quit India Resolution was ratified at the Congress meeting at Gowalia Tank, Bombay, on August 8, 1942. Hence option (a) is the correct answer.
