Q. Quit India Movement was launched in response to (UPSC Prelims 2013)
Answer: Cripps Proposals
Notes: The correct answer is [B] Cripps Proposals. The Quit India Movement, also known as the August Movement or August Kranti, was launched by Mahatma Gandhi on August 8, 1942, during the Bombay session of the All-India Congress Committee.

• Failure of Cripps Mission (Statement B is Correct): In March 1942, the British government sent Sir Stafford Cripps to India to negotiate terms for Indian cooperation in World War II. The Cripps Proposals offered "Dominion Status" after the war and a constituent assembly, but it gave the provinces the right to secede from the Indian Union. The Congress rejected it as it did not offer immediate complete independence and introduced the "blueprint for partition." Gandhi famously described the proposal as a "post-dated cheque on a crashing bank." The failure of these talks led directly to the call for "Do or Die" (Karo ya Maro).
• Cabinet Mission Plan (Statement [A] is Incorrect): The Cabinet Mission arrived in India in 1946, four years after the Quit India Movement. Its purpose was to discuss the transfer of power and the formation of a Constituent Assembly.
• Simon Commission Report (Statement [C] is Incorrect): The Simon Commission submitted its report in 1930. The agitation against it occurred in the late 1920s, which eventually led to the Civil Disobedience Movement, not the Quit India Movement.
• Wavell Plan (Statement [D] is Incorrect): The Wavell Plan was proposed at the Simla Conference in 1945. It was an attempt to resolve the political deadlock between the Congress and the Muslim League regarding the formation of an interim government after the Quit India Movement had already subsided.

The Quit India Movement was unique because it was largely leaderless after the British government arrested all the top Congress leaders (Operation Zero Hour) in the early hours of August 9, 1942. This led to a spontaneous mass uprising across the country.
