Question

in 1954, after the french were defeated at dien bien phu,
○ communists took control of all of vietnam.
○ vietnam was divided at the 17th parallel.
○ an international committee gave vietnam back to france.
○ the united states sent troops to vietnam to remove the communists.

Explanation:

After the French defeat at Dien Bien Phu in 1954, the Geneva Accords led to Vietnam being divided at the 17th parallel (North and South Vietnam). Communists didn't take all of Vietnam then, an international committee didn't give Vietnam back to France, and the US sent troops later (not immediately in 1954).

Answer:

B. Vietnam was divided at the 17th parallel.
