The event described in the diagram is the Korean War. Therefore, option b. The Korean War should be placed in the center of the diagram.

To determine which event should be placed in the center of the diagram, let's analyze the given information:

1. "Country divided at 38th parallel": This refers to the division of Korea into North Korea and South Korea along the 38th parallel after World War II.

2. "Communists invade from the north": This suggests that the event involves a communist invasion from the northern part of the divided country.

3. "Fighting stops in 1953": This indicates that the conflict lasted until 1953 and then came to a halt.

Based on this information, the most suitable event to be placed in the center of the diagram is "The Korean War" (option b). The Korean War was fought from 1950 to 1953 between North Korea, supported by China and the Soviet Union, and South Korea, supported by a United Nations coalition led by the United States.
