The correct answer is: A. Abul Kalam Azad.
Abul Kalam Azad was a freedom fighter, educationist, and politician who served as the first Education Minister of India. He was also the President of the Indian National Congress from 1940 to 1946.
In the Ahmedabad session of the Indian National Congress in 1920, Azad proposed to adopt Complete Independence as the goal of the Congress. This proposal was accepted by the Congress, and it marked a significant turning point in the Indian independence movement.
The other options are incorrect because:
- Hasrat Mohani was a freedom fighter who was also a member of the Indian National Congress. However, he did not propose to adopt Complete Independence as the goal of the Congress.
- Jawaharlal Nehru was a freedom fighter and the first Prime Minister of India. He was also a member of the Indian National Congress, but he did not propose to adopt Complete Independence as the goal of the Congress.
- Mohandas Karamchand Gandhi was a freedom fighter and the Mahatma of India. He was also a member of the Indian National Congress, but he did not propose to adopt Complete Independence as the goal of the Congress.
