What technological achievement did the soviet union make during this time? (the time of the cold war) a. developing the hydrogen bomb b. building the suez canal c. launching sputnik d. creating the massive retaliation theory

The correct option is "c. launching Sputnik"

Sputnik 1, launched on October 4, 1957 by the Soviet Union, was the first artificial satellite in history. Sputnik 1 was the first of several satellites launched by the Soviet Union in its Sputnik program, most of them successful. Sputnik 2 followed, as the second satellite in orbit . The first failure was suffered by Sputnik 3.

The launch of this satellite opened the way to the spatial development of the USA and therefore the space race of both powers.
