The correct answer is: a) Imphal.
The Quit India Movement was a major movement launched by Mahatma Gandhi on 8 August 1942, demanding the British to quit India. The movement was launched in response to the failure of the Cripps Mission to resolve the Indian independence issue. The movement was met with severe repression by the British, and many leaders were arrested. However, the movement had a significant impact on the Indian independence movement, and it is considered to be one of the major turning points in the history of India.
The Quit India Movement had significant participation in the Imphal region of Manipur. The people of Imphal were inspired by the speeches of Mahatma Gandhi and other leaders of the movement, and they took to the streets in protest against British rule. The British responded to the protests with violence, and many people were killed or injured. However, the people of Imphal continued to protest, and the movement eventually led to the end of British rule in India.
The other options are incorrect because they are not regions of Manipur.
