Correct option is B
The correct answer is (b) Act of 1947
This refers to the Indian Independence Act of 1947, which was passed by the British Parliament in July 1947. The Act declared that British rule in India would end, and it set a deadline for the transfer of power to be no later than June 30, 1948. However, the actual transfer of power happened sooner, on August 15, 1947, leading to the independence of India and the creation of Pakistan.
