Which statement correctly describes the outcome of the Vietnam War?

• A. The country remained divided at the end of the conflict.
• B. The United States maintained a long-term government in South Vietnam.
• C. The war ended in 1969.
• D. The country was unified under communist rule in 1975.

Answer: (D)

The key idea is that the Vietnam War ended with the country united under a single, communist government. When North Vietnamese forces captured Saigon in 1975, South Vietnam collapsed and the two Vietnams were brought together as the Socialist Republic of Vietnam. Although formal reunification was completed a year later in 1976, 1975 marks the end of the war and the moment of unified control under communism. The United States had already withdrawn its forces by 1973 and did not maintain a long-term government in the south, so that part doesn’t fit. The war did not end in 1969, and the country was not left divided at the end.
