The answer is C: Strict enforcement of the Neutrality Acts.
Explanation for each option:
A. The sale of "surplus" weapons and military supplies to Great Britain: This is correct. Before the U.S. entered World War II, President Franklin D. Roosevelt supported measures to aid Great Britain, including the sale of surplus weapons and military supplies. This was part of his efforts to support the Allies while maintaining official neutrality.
B. Trading 50 overage destroyers for leases to eight naval bases: This is correct. Known as the Destroyers for Bases Agreement, this deal was made in 1940 between the United States and the United Kingdom. The U.S. provided 50 aging destroyers to Britain in exchange for land rights on British possessions for the establishment of naval and air bases.
C. Strict enforcement of the Neutrality Acts: This is incorrect. While the Neutrality Acts were initially enforced to keep the U.S. out of foreign conflicts, Roosevelt sought ways to aid the Allies despite these restrictions. He gradually moved away from strict enforcement, culminating in measures like the Lend-Lease Act, which allowed the U.S. to supply military aid to foreign nations during the war.
D. The first peacetime draft in American history: This is correct. The Selective Training and Service Act of 1940 was enacted before the U.S. entered the war, marking the first peacetime conscription in American history. It was part of Roosevelt's efforts to prepare the nation for potential involvement in the conflict.
