Final answer:
The civilian zone that refuted military rescue in the context of the Vietnam War was the South Vietnamese government.
Step-by-step explanation:
In the context of the provided information, the civilian zone that refuted military rescue was the South Vietnamese government. During the Vietnam War, many South Vietnamese officials and soldiers were imprisoned or executed by the North Vietnamese if they were captured.
The United States military and civilian officials risked their lives to rescue these individuals, but most were unable to escape. As a result, hundreds of thousands of South Vietnamese soldiers and officials were imprisoned, and many Vietnamese civilians became refugees in neighboring countries.
