Solution

The correct option is D six times
The force due to gravity of the moon is approximately one-sixth as that of the earth.The force exerted by the ground on a standing person is equal and opposite to the force the person applies on the ground (By Newton's third law). Thus, the force exerted by the ground on a person standing on earth is roughly six times the force exerted by the ground on a person standing on the moon.
