What was the “missile gap” identified in the 1950s?

The “missile gap” was the perceived Soviet lead in intercontinental ballistic missiles (ICBMs) during the 1950s. Reports and political claims suggested that the USSR was ahead of the United States in ICBM development, although later evidence showed that the size of this gap had been exaggerated. Therefore, the correct choice is “The USSR, according to a report, was ahead in ICBM technology.”
