Question

Which nations provided military aid to North Vietnam during the Vietnam War?

Answer 1

The correct answer is D.

The Vietnam war was a military conflict that occurred in Vietnam, Laos and Cambodia between 1955 and 1975.

Both China and the Soviet Union supported North Vietnam (logistic and military). Both nations hoped to consolidate and expand communism in the Asian hemisphere. Western governments condemned North Vietnam as a puppet state and a slave to Beijing and Moscow.

The war ended when the North Vietnamese forces defeated South Vietnam. In 1976 the two parts of the country were reunited and the Socialistic Republic of Vietnam founded.  

Answer 2

I know that it has nothing to do with France, because they fought the US and France, so the only one could be D, China and Soviet Union.
