Explanation:

The 1957 launch of Sputnik I, the first artificial satellite by the Soviet Union, triggered immediate U.S. concern over Soviet technological superiority in the Cold War. This directly escalated the space race, as the U.S. rushed to develop its own space capabilities to compete with the USSR. The other options are incorrect: there was no immediate push for new fuel sources, space regulation was not an immediate focus, and peaceful coexistence (a Cold War phase) did not end due to Sputnik alone.

Answer:

C. heightened the space race as a form of Cold War competition
