When did the Non-Cooperation Movement end?

1922

The correct answer is Option 3- 1922

The Non-Cooperation Movement ended in 1922.

The Non-Cooperation Movement was a nationwide civil disobedience movement launched in 1920 by Mahatma Gandhi and the Indian National Congress (INC) to protest against the British Raj's Rowlatt Acts and the Khilafat issue. The movement called for Indians to boycott British goods and institutions, resign from government jobs, and refrain from paying taxes.

The movement was initially successful in mobilizing millions of Indians. However, it was called off by Gandhi in 1922 following the Chauri Chaura incident, in which a violent mob of protesters set fire to a police station, killing 22 policemen.

Despite its relatively short duration, the Non-Cooperation Movement had a significant impact on the Indian independence movement. It helped to popularize Gandhi's methods of non-violent resistance and inspired millions of Indians to join the struggle for freedom.
