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

The correct answer is B) The end of American neutrality in World War II.

The Lend Lease Act was a law passed by president Franklin D. Roosevelt. This law allowed certain countries like China, Great Britain, and France, to borrow military weapons and supplies from the United States. This officially breaks the policy of neutrality, as it shows that the United States supports the Allied powers in the war. This action would cause tension between the US and the Axis powers (like Japan, Germany, and Italy).
