Which of the following district was not in West Bengal at the time of Independence of India ?
Explanation
Why Correct: Coochbehar was a princely state that acceded to India on August 28, 1949, and merged with West Bengal on January 1, 1950, making it not part of West Bengal at Independence (August 15, 1947).
Distractor Analysis: Howrah was a district in Bengal Presidency since 1843 and remained in West Bengal after partition. Darjeeling was part of Bengal Presidency since 1866 and remained in West Bengal. Murshidabad was a district of Bengal that was controversially assigned to West Bengal despite Muslim majority during the 1947 Radcliffe Line partition.
Takeaway: The princely states of Coochbehar, Tripura, and Manipur acceded to India after Independence and were later integrated into states through mergers in 1949-1950.
