The correct answer is A) fear of communism and the USSR was increased.
A result of the trial and execution of Ethel and Julius Rosenberg for espionage in 1953 was that fear of communism and the USSR was increased.
During the Cold War years, the United States and the Soviet Union competed in almost everything, including in the arms race and the space race. During this period, the world lived tense moments and even, the world was on the brink of another war due to the Cuban Missile Crisis of 1962.
In the case of Ethel and Julius Rosenberg, they were executed because the government proved that they had given top-secret information to the Soviet Union, regarding nuclear bombs. They were accused of being spies and of conspiring against the United States. These events and all the scenario of the Cold War and the Red Scare accusations of the US having Communists infiltrated in the federal government and in the military, only increased the fear of communism and the USSR.
