Which problem of mass movements did the Chauri Chaura incident expose?

Correct answer: Difficulty of maintaining nonviolent discipline

The direct answer is A: difficulty of maintaining nonviolent discipline. The Chauri Chaura incident occurred in February 1922 during the Non-Cooperation Movement. A crowd became violent and killed policemen by burning a police station. Gandhi believed that a mass movement based on ahimsa could not continue if participants lost self-control, so he withdrew the movement. Thus the incident exposed the danger of violence and weak discipline in a large public movement. Option A is correct because it states this exact problem. Option B is wrong because complete independence was the national aim, not the problem exposed by the incident. Option C is wrong because the event did not show public support for British rule. Option D is unrelated: Company revenue belongs to an earlier phase of colonial history, not this incident. Memory cue: Chauri Chaura means violence, discipline, and withdrawal of Non-Cooperation.
