Dr. B.R. Ambedkar was originally elected to the Constituent Assembly from undivided Bengal. After the partition layout of 1947, from which province was he re-elected to ensure his presence in the Drafting Committee?

Explanation

Dr. Ambedkar was initially elected from Eastern Bengal, which became part of Pakistan after partition. To secure his invaluable expertise, the Congress leadership ensured his re-election from the Bombay Presidency (by making M.R. Jayakar resign from his seat), integrating him back into the drafting machine.
