Passage of the Lend-Lease Act in 1941 signaled the entry of the United States into World War II. the end of American neutrality in World War II. the start of American neutrality in World War II. the decision of the United States to back the Axis powers.

Respuesta :

The end of neutrality and the official support of the allies. 

The correct answer is: "the end of American neutrality in World War II"

The Lend-Lease Act was a program enacted in the US in 1941 to provide support to Allied countries so that they could defeat the axis forces (nazi Germany, fascist Italy and the Japanese Empire) in WWII, but the US had not decided to directly participate in the conflict yet.

The program consisted on the distribution of  food, oil, and all types of military materials and it remained functioning since 1941 until the end of the conflict in 1945.
