Answer 1

I think it was D. Basically the US sent South Vietnam troops because they feared Vietnam would become communist, which would spread to the rest of Asia. The US sent supply and materials to South Vietnam to help the spread. I don't know if the answer that best suits that is D, but that's what I would say.

Answer 2

D) The United States sent troops to Vietnam in order to STOP THE NORTH FROM CONTROLLING THE SOUTH.
