Which limitation of the Non-Cooperation Movement is revealed by the Chauri Chaura incident?

Correct answer: Maintaining non-violent discipline in a huge mass movement was difficult

The governing concept is the difficulty of maintaining common discipline in a large and diverse movement. Non-Cooperation attracted people with different local grievances, and intense anger could sometimes lead to actions beyond the approved non-violent method. Chauri Chaura demonstrated this danger when a protest became violent, prompting Gandhi to suspend the campaign. Option A is correct; the other choices deny mass participation, rural involvement or the Congress commitment to non-violence.
