The correct answer is option 4, Calcutta. In 1920, the Indian National Congress passed the famous resolution on "Non-Cooperation" during its session in Calcutta. This resolution marked a significant shift in the Congress`s approach towards the British rule in India. It advocated for Indians to refuse to cooperate with the British government, including boycotting British goods, educational institutions, and legal systems. The Non-Cooperation Movement aimed to exert pressure on the British government and create a sense of unity among Indians in their struggle for independence. It gained widespread support and participation across the country, but ultimately, it was called off due to incidents of violence. Nonetheless, the Non-Cooperation Movement played a crucial role in shaping the Indian independence movement.
