The correct answer is D, as the Soviet Union exerted strict control over its media, while the United States didn't.
Censorship in the Soviet Union was a persuasive phenomenon of state ideological pressure that was valid throughout the history of that country (1922-1991), although with certain ups and downs. There were two periods of relaxation: the first, after the death of the dictator Joseph Stalin in 1953, and the second during the politics of glasnost ("transparency") launched by Mikhail Gorbachev in 1986.
Absolutely all the press media within the Soviet Union were strictly controlled by the State, whether it was radio, television, books, magazines and newspapers. This was achieved through the exclusive state ownership of all facilities dedicated to production, so that its members must necessarily be employees of the State. This also extended to the fine arts, including theater, opera and ballet. Music concerts and art exhibitions could only be held in controlled places previously authorized by the State.
