Answer:
C) provided lend-lease assistance to the Allies.
Step-by-step explanation:
While formally remaining a neutral country in 1939, 1940 and until December 1941, the United States passed the Lend-Lease Act and this allowed Great Britain to buy American war supplies and materiel from the US. The act made it possible to the US to lend or lease those supplies to "nations vital to the defense of the Unites States," the law said.
