The correct answer is A) launching of Sputnik.
On October 4, 1957, the Soviet Union successfully launched Sputnik into space. This satellite made by the Soviet Union was the first satellite that orbitted the Earth. The success of this satellite showed the technological superiority of the Soviet Union during this time, as America had not accomplished this feat yet. This is why the Soviet government used this as a means of propaganda, to show that the Soviet Union was more advanced than the United States.
