• A. Cold War
• B. Moon Race
• C. Space Race
• D. Space Exploration

Answer: (C)

The main idea here is recognizing a specific name for the rivalry between two nations to achieve milestones in spaceflight. This competition is called the Space Race because it describes a race-like push to reach space achievements—launching satellites, sending humans into orbit, and ultimately landing on the Moon—driven by the Cold War context. The broader Cold War refers to overall political and military tension between the United States and the Soviet Union, not just space efforts. Moon Race is a casual shorthand that focuses only on lunar goals rather than the full breadth of space milestones, and Space Exploration is a general term for studying space without capturing the competitive, national rivalry aspect.
