Why did taking grain from peasants under War Communism become both a benefit and a problem for the Bolsheviks?

Correct answer: It supplied grain to the army and cities but also increased peasant discontent

During the Civil War, the Bolshevik government needed reliable food supplies for the Red Army and for workers in towns. Grain requisitioning helped it collect food directly from the countryside, so it was useful for maintaining the army and urban centres. However, compulsory collection reduced the incentive for peasants to produce or surrender surplus grain, especially when they received little in return. Resentment, resistance and rural unrest consequently grew. Option A correctly identifies this double effect. Options B, C and D have no connection with the purpose or results of grain requisitioning under War Communism.
