AI-generated practice question — model-generated for extra practice, not a previous-year CBSE board question.
(A) Both A and R are true and R is the correct explanation of A.
Gandhiji called off the Non-Cooperation Movement in February 1922 after the violent incident at Chauri Chaura, as satyagrahis needed proper training to sustain a non-violent mass struggle.
The textbook (Fig. 5 caption) states that at Chauri Chaura, Gorakhpur, a peaceful demonstration turned violent, after which Gandhi halted the movement. The Reason correctly explains his concern that the movement was turning violent and that participants needed better training in non-violence — making (A) the right choice. Remember: both statements are factually correct AND the Reason directly explains the Assertion.
