Final answer:
The centripetal acceleration of the Moon is caused by gravitational pull from the Earth.
Step-by-step explanation:
The centripetal acceleration of the Moon is caused by Gravitational pull (Option B).
The Moon orbits around the Earth due to the force of gravity between them. Gravity is the attractive force that exists between any two objects with mass. In this case, the Earth's gravitational force acts as the centripetal force, constantly pulling the Moon towards the Earth, making it move in a curved path.
The centripetal acceleration of the Moon is almost equal to the acceleration due to Earth's gravity, with less than 1% difference between them. This is because the Moon's orbit is slightly elliptical, and the Earth-Moon system rotates about its center of mass, which is located below Earth's surface. All these factors contribute to the Moon's circular motion.
