Question

by the time the korean war ended in 1953,
china had seized the peninsula, annexing korea.
korea was united under a democratic government.
the division of the korean peninsula remained unchanged.
korea was united under an independent communist government.

Explanation:

The Korean War ended in 1953 with an armistice, not a peace treaty. This armistice maintained the division of the Korean Peninsula along the 38th parallel, creating North Korea and South Korea as separate entities. None of the other options align with historical facts: China did not annex Korea, Korea was not united under a democratic or communist government after the war.

Answer:

the division of the Korean peninsula remained unchanged.
