D. The president airlifted supplies to keep the Soviet Union from taking Berlin.

Explanation:

I think the answer is D. According to a source, "The U.S. government was shocked by the provocative Soviet move, and some in President Harry S. Truman's administration called for a direct military response. Truman, however, did not want to cause World War III. Instead, he ordered a massive airlift of supplies into West Berlin."

the big stick policy was to still look powerful, and be nice at the same time. the big stick policy was also to countries who were at war, find peace with eachother.

the dollar diplomacy was to expand american business and get it to latin america, for that would be good for the economy.
