Hint: There are two types of forces (1). Contact force (2). Non-contact force

Contact force –It is defined as any force that requires contact to occur with some motion between two contact surfaces and that results into a contact force.

Non-contact force – It is defined as a force which acts on objects that are not in physical contact.

Complete step-by-step answer:
So out of the above options gravitational force and magnetic force are non- contact force as there is no requirement of two objects to come in contact.

Magnetic force – Let us take an example of magnetic force, if we take the example of magnets, we find that two magnet bars if placed near to each other with north pole and south pole in opposite directions they will attract as the unlike poles attract and now contrary to this if north poles of two magnet bars are placed opposite to each other then they repel each other as like poles repel each other.

Gravitational force - If we consider the example of an old incidence that once Newton sitting beneath the apple tree found a ripe apple fallen off the tree gave him the idea of a force which made the apple to fall down called a gravitational force. So, we consider this force as a force of attraction between two objects having mass. This force gets two objects together.

Therefore, the correct option is D.

Note – Whenever we come up with this type of question, one must know the concept of force that is defined as a mechanism of push or pull effect that acts on an object when it interacts with something or one can say that forces of repulsion and attraction. By using this basic concept we can easily solve questions related to force.
