Solution

The correct option is C on Earth's surface
The magnitude of force of gravity is greatest on the surface of the earth because the value of acceleration due to gravity has its maximum value on the surface of the earth i.e., $9.8 m s^{- 2}$ .
Its value decreases as we move away from the surface of the earth that is either moving above the surface of the earth or towards the center of the earth and the value of acceleration due to gravity at the center of the earth is zero.
