Answer:
B The decline of the Red Scare
Step-by-step explanation:
"Red Scare", was a movement initiated by Joseph McCarthy that established violent investigations against any term or suspected of sympathizing with any element related to communism or the Soviet Union. During this period McCarthy became a well-known and sought-after name, but investigations and accusations against Communist sympathizers and allies were often abusive. McCarthy's rejection as senator marks the end of that period and the "Red Scare" movement.
