Correct answer: A. Demand for revenue relief during crop failure
Explanation: Direct answer: Option A, the demand for revenue relief during crop failure. Kheda Satyagraha took place in Gujarat in 1918. The crop yield was seriously affected, and peasants argued that when crops failed they should not be forced to pay the full land revenue. Gandhi and Vallabhbhai Patel helped organise them around a peaceful, collective refusal to pay revenue until relief was granted. Step by step, poor harvest reduced farmers’ ability to pay; the government still demanded revenue; the movement therefore sought suspension or remission of the demand. Option A is correct. Option B belongs to the later Salt Satyagraha and is not the central issue at Kheda. Option C is unrelated: the peasants were not organised to cut trees. Option D is also unrelated and contradicts the non-violent, anti-colonial character of the movement. Memory cue: Kheda means Gujarat, 1918, crop failure, and tax relief.
