Answer 1

Correct answer is A. turned over documents proving that Soviets were trying to infiltrate the U.S. government.

Step-by-step explanation:

Option A is correct because this event created a massive retaliation in the United States, where many people were marked as Communists, sometimes even without evidences.

Venona project was started during WW2 with a goal to decrypt messages that were sent by Soviet intelligence agencies.

McCarran Act was introduced in 1950, with a goal to act against Communism in US.

D is also not correct as many in Hollywood were marked as Communist and there were testimonies against them even on courts.
