_____ reversed Lenin's New Economic Policy and started "Five-Year Plans." A) President Franklin D. Roosevelt B) Adolf Hitler

The correct answer is B) Adolf Hitler.

Adolf Hitler, as the Chancellor of Germany and later the dictator of Nazi Germany, implemented economic policies that included the reversal of Lenin's New Economic Policy (NEP) in the Soviet Union. Hitler did not directly reverse Lenin's policy, but he did adopt and implement his own economic plans known as the "Four-Year Plan" and later the "Five-Year Plans" in Germany.

These economic plans, introduced by Hitler, aimed at transforming the German economy by prioritizing rearmament, increasing military production, and achieving economic self-sufficiency, especially in strategic resources like steel, coal, and synthetic materials. The emphasis on central planning and state control over production and resources in the Five-Year Plans had similarities with the economic policies of the Soviet Union, although the ideologies and objectives were fundamentally different between Nazi Germany and the Soviet Union.
