a. to make money for welfare programs.
b. to stop the spread of drugs.
c. to teach vietnamese children about democracy
d. to fight the spread of communism.

D) To fight the spread of communism.

Because of the Domino Theory they thought that if Vietnam fell into Communism, the whole region would follow. So therefore they wanted to support South Vietnam in order to contain Communism in Asia.

The answer is:

D.(To fight the spread of communism)
