The correct option is A Poona Pact
Poona Pact was an agreement between Dr. Babasaheb Ambedkar and Mahatma Gandhi signed on September 24, 1932, at Yerwada Central Jail in Pune, to break Mahatma Gandhi's fast unto death. Poona pact was the result of the communal award granted in 1932 by the British government. Mahatma Gandhi objected to the provision of separate electorates for the Scheduled Castes, which in his view separated them from the whole Hindu community.
