Which action from the combination of gravitiy and interia on the moon

Moon's orbit around the earth.

Option: (A)

Explanation:

The gravity between the moon and the earth pulls them together, but since earth has much larger mass, the acceleration due to the force is felt quite larger by the moon. Newton's first law stating that an object stays in motion, once set in motion without a resistant force, thus making the moon keep revolving around the earth. The gravity acts as the centripetal force that prevents the moon from going forward in a straight line and keeps it moving in a orbit around the earth, thus making this option the correct one.
