Correct option is C
The correct answer is (c) Gravitational force.
· Gravitational force is a natural phenomenon by which all objects with mass are attracted towards each other.
· This force is described by Newton's Law of Universal Gravitation, which states that every point mass attracts every other point mass in the universe with a force proportional to the product of their masses and inversely proportional to the square of the distance between them.
· On Earth, this force gives weight to physical objects and causes objects to fall towards the ground when dropped.
· Gravitational force is responsible for the orbits of planets around the Sun and the motion of moons and satellites.

Spring Force:
· Spring force is the force exerted by a compressed or stretched spring upon any object attached to it.
· It follows Hooke's Law, which states that the force exerted by the spring is proportional to the displacement, i.e., F=−kxF = -kxF=−kx, where kkk is the spring constant and xxx is the displacement.
Mechanical Force:
· Mechanical force refers to the force exerted by a machine or in mechanical systems.It involves physical interaction between objects, such as pushing or pulling forces, tension, compression, and torsion.
Friction Force:
· Friction force is the resistive force that occurs when two surfaces move or attempt to move across each other.It acts in the opposite direction to the motion and is influenced by the nature of the surfaces and the normal force pressing them together.
