The correct answer is Mahatma Gandhi. After India achieved independence, Gandhi believed that the Indian National Congress, having served its political purpose, should be disbanded and instead reorganized as a body to serve the people socially and economically.
Option 1, C. Rajagopalachari, and Option 4, Jayaprakash Narain, were prominent figures in Indian politics post-independence but they did not suggest the dissolution of the Indian National Congress.
Option 2, Acharya Kripalani, was the president of the Indian National Congress at the time of independence. Although he had disagreements with the direction the Congress was taking post-independence, he is not known for suggesting the dissolution of the organization.
Thus, each option represents a significant leader in Indian history, but it was Mahatma Gandhi who suggested the Congress`s dissolution after independence.
