When did Quit India Movement start ? 

August 1942

The correct answer is Option (2) → August 1942

The Quit India Movement, also known as the August Movement, was launched by Mahatma Gandhi and the Indian National Congress on August 8, 1942. The immediate reason for launching this movement was the Failure of the Cripps Mission.

After the failure of the Cripps Mission, Mahatma Gandhi decided to launch his third major movement against British rule. This was the “Quit India” campaign, which began in August 1942. Although Gandhiji was jailed at once, younger activists organised strikes and acts of sabotage all over the country. Particularly active in the underground resistance were socialist members of the Congress, such as Jayaprakash Narayan. In several districts, such as Satara in the west and Medinipur in the east, “independent” governments were proclaimed. The British responded with much force, yet it took more than a year to suppress the rebellion.
