The correct answer is option D that is on an frictionless surface ::


Lets look out the Options carefully


A) We all know that at the centre of the earth the value of $g$ is zero as there may not be any heavy whole mass.


B) During a free fall the body fall under the action of gravity and does not contain any weight as the gravtional force comes in action between stationar objects or when not in the path of gravtional attaraction of any body to the same.


C) It will also remain zero when that body is present in an interplanetary space. Because then there will not be gravity and not acceleration will be produced due to it.


D) On an frictionless surface the force of friction is definitely zero but the force of attaraction/gravity is present and the weight depends on the force of attaraction/gravity.


W = mg
