The correct answer is A. Lahore.
The Lahore session of the Indian National Congress was held in September 1920. It was at this session that the famous resolution on Non-Cooperation was adopted. The resolution was moved by Mahatma Gandhi and was passed by a large majority. The resolution called for a boycott of British goods and institutions, as well as a withdrawal of cooperation from the British government. The Non-Cooperation Movement was a major turning point in the Indian independence struggle. It was the first time that the Indian people had come together in such a large and united way to oppose British rule. The movement was successful in achieving many of its goals, including the release of political prisoners and the granting of greater self-government to India.
