The non-cooperation movement of Gandhiji was launched in which of the following year?

Correct option is C

The Non-Cooperation Movement (1920-1922) was launched by Mahatma Gandhi in response to the Jallianwala Bagh massacre, the Rowlatt Act, and the Khilafat Movement. The movement called for boycotting British goods, institutions, and services to force the British government to grant self-rule. It ended in 1922 after the Chauri Chaura incident, where violent clashes led Gandhi to withdraw the movement.
