The correct answer is A) It gave them war supplies.
The US lend-lease program of 1939 helped the Allies in that it gave them war supplies.
Let's have in mind that President Franklin D. Roosevelt had decided to maintain the foreign policy of neutrality at the beginning of World War II. However, the US federal government created the so-called Lend-Lease Act of 1939 in order to support countries such as France and Gretad Britain in the war effort. The argument to lend and lease to these countries was that their role was important to keep the United States' economic and political interests safe.
That is how the US federal government create valid legislation to give a helping hand to its long-time allies that were fighting in Europe giants the Germans and Italian troops.
Conditions changed and after Japan's Pearl Harbor attack in December 1941, President Roosevelt asked Congress for a declaration of war against Germany. That is how the US entered World War II.
