Answer:
B. Communist ideas were seen as a threat to freedom.
Step-by-step explanation:
The communist ideas promoted by the Soviet Union require the government to take complete control over the people's freedom to choose and ownership of resources.
The government technically own all the things in the country and the people did not have a freedom to choose their careers. On top of that, they're openly giving punishment to the people who were not afraid to criticize the government. Censoring the media along the lines to made sure that people did not think badly about the government.
United States viewed this as a threat to freedom. This was the reason for the cold war that occurred between United States and Soviet Union between 1947 – 1991.
