Solution

The correct option is D centrifugal acceleration negates the acceleration due to gravity
The satellite rotates in a circular path or elliptical path such that gravitational pull is always balanced by centrifugal force due to the rotational motion of satellite.
Thus a body in the satellite will feel weightlessness.
although force of gravity on a body is never zero but it is balanced by centrifugal force in this case.
so option D is correct.
