Answer:
The correct answer is C. The Vietnam War ended with the American troops finally withdrawing from Vietnam.
Explanation:
The Vietnam War took place from about 1955 to 1975 in and around Vietnam. North Vietnam and the National Front for the Liberation of South Vietnam (the "Vietcong") were facing the US and South Vietnam. Since the conflict immediately followed the Indochina War (1946-1954) between the colonial power of France and the Vietnamese independence movement of Việt Minh and extended to all of Indochina, it is also called Second Indochina War. Because of the directly and indirectly involved superpowers, it is considered a proxy conflict in the Cold War. It ended with the victory of North Vietnam and the first US military defeat in its history.
