How many days are taken by the moon to complete a single rotation on its axis?

Correct option is D

The correct answer is (d) 27.3 earth days.
· The Moon takes approximately 27.3 Earth days to complete one full rotation on its axis.
· This period is known as a sidereal month, which is the time it takes for the Moon to return to the same position against the background of stars.
· This rotation period is synchronized with the Moon’s orbit around the Earth, resulting in the same side of the Moon always facing the Earth, a phenomenon known as synchronous rotation or tidal locking.
