C
It is a force that make objects remain in their position
Explanation: 

Detailed explanation-1: -Gravitational force is an attraction between masses. The greater the size of the masses, the greater the size of the gravitational force (also called the gravity force). The gravitational force weakens rapidly with increasing distance between masses.

Detailed explanation-2: -Gravity is a force which tries to pull two objects toward each other. Anything which has mass also has a gravitational pull. The more massive an object is, the stronger its gravitational pull is. Earth’s gravity is what keeps you on the ground and what causes objects to fall.

Detailed explanation-3: -The gravitational force is a force that attracts any two objects with mass. We call the gravitational force. It is given by, F=Gm1m2r2, direction of force will be always towards the other mass along the line joining the two bodies.

Detailed explanation-4: -Definition. The gravitational force would be described as a force of attraction (attractive force) that attracts all physical forms having mass. It is by far the weakest recognized natural force.

Detailed explanation-5: -Earth attracts all things towards it through an unseen force of attraction. This force of attraction is called as gravitation or gravitational pull.
