A Correct answer
Explanation

There are indeed mirrors on the Moon - retroreflectors placed by Apollo missions (11, 14, and 15) and Soviet Lunokhod rovers. These mirrors allow astronomers to laser-range the Moon, measuring the precise Earth-Moon distance. They are still used today for scientific research and have helped confirm general relativity.
