Answer 1

Sorry I might be too late for this, but The answer is C: It was the idea that if one nation fell to communism, others would soon follow the example.

Step-by-step explanation:

This was a huge fear that the Americans had during LBJ's presidency. They feared that if South Vietnam fell to communism, others countries like Laos, Thailand, and other Southern Asian countries would also too. This eventually led to the US sending troops to South Vietnam therefore starting the declaration of the Vietnam War.
