The correct answer is A. The name of this phenomenon was McCarthyism.

Explanation:

McCarthyism describes a period of recent US history in the early stages of the Cold War. It was characterized by a loud anti-communism and conspiracy theories, and is also known as Second Red Scare. Although Joseph McCarthy only made public appearances from 1950 to 1955, the entire period of persecution of real or alleged communists and their sympathizers from 1947 to about 1955 is now known as the McCarthy era.

McCarthyism is considered to have ended in January 1955, when Joseph McCarthy resigned from the presidency of the Senate Government Operations Committee following a motion of censure against him voted by the Senate.
