The question is incomplete. complete question is attached belowanswer: correct answer is option b  i.e.  solid particles  reason: filter paper has small pores, through which smaller particles can pass through. however, solid particles  have relatively larger size. hence, they are least likely to pass through.

The answer is falsegravitational force is independent of medium and depends only on the masses of the two objects and the distance between them.
