Whom did the grain requisition policy under War Communism affect?

Correct answer: Peasants

Grain requisition under War Communism directly affected peasants because the state forcibly collected grain from the countryside to supply the army and urban populations during the Civil War. The policy was intended to deal with wartime shortages, but it reduced the amount of produce peasants could keep or exchange and therefore created resentment, resistance, and hardship in rural areas. Option A is correct because peasants were the producers from whom grain was taken. Option B is unrelated: foreign monarchs were not the targets of this domestic agricultural policy. Options C and D describe occupations that were not the central social group affected by grain collection. The policy therefore illustrates the tension between emergency state control and peasant interests.
