The correct answer is A.
The Good Neighbor Policy was a name given to United States foreign policy towards Latin America during the administration of President Franklin D. Roosevelt.
The policy's main principle was that of non-intervention and non-interference in the domestic affairs of Latin America. The goal of this policy was to create new economic opportunities and strengthen the United States influence in Latin America.
The policy's success was measured in part by the rapidity with which most of Latin America states rallied to the Allies during World War II.
