Which force is responsible for the motion of the moon around earth?

Correct option is D

The force responsible for the motion of the Moon around the Earth is the gravitational force.
 Gravity is the force of attraction between two objects that have mass. The Earth has a large mass, and therefore exerts a gravitational force on the Moon, which causes it to orbit the Earth.
 The Moon is constantly pulled towards the Earth by its gravitational force, but it also has enough momentum to continue moving in a circular path around the Earth.
 This balance between gravitational force and momentum is what keeps the Moon in orbit around the Earth.
