The correct answer is A) The start of the Cold War.
The Second Red Scare saw a rise in fear among American citizens and members of the federal government. This fear was rooted in the possible spread of communism and power of the Soviet Union after World War II. At the end of World War II, the US and Soviet Union emerged as the two biggest global superpowers. This rivalry between the two would result in the Cold War, where the US would constantly pursue a policy of stopping the spread of communism on an international scale.
