Correct option is D

The correct answer is (d) Chauri Chaura.
· The Non-cooperation Movement was called off by Mahatma Gandhi in 1922 after the violent incident at Chauri Chaura, a small town in Uttar Pradesh.
· In this incident, a protest by peasants turned violent, and a mob set fire to a police station, resulting in the death of 22 policemen.
· Gandhi, a staunch advocate of non-violence, was deeply disturbed by this event and decided to halt the movement, as it had deviated from the principles of non-violent civil disobedience.
Information Booster:
· Rowlatt Act: Passed in 1919, this act allowed the British government to imprison any person suspected of terrorism without trial, which led to widespread protests, but it was not the reason for calling off the Non-cooperation Movement.
· Khilafat Movement: This was a parallel movement to the Non-cooperation Movement, aimed at supporting the Ottoman Caliphate, but it was not the cause of the movement's suspension.
· Quit India Movement: This was a different movement launched by Gandhi in 1942 to demand an end to British rule in India and was not related to the Chauri Chaura incident.
