Hint: From the concept of the Law of conservation of momentum, we can say that when two bodies are colliding with each other, the summation of their momentum before the collision is equal to the summation of momentum after the collision. It means that the system's momentum is conserved, and this Law is called the Law of momentum conservation.

Complete step by step solution:
From the concept of Newton's Third Law, we can say that if a force is acting on a body, then the body will also apply a force of the same magnitude as that of applied force but in the opposite direction.

The Law of momentum conservation can be derived from the third Law of Newton as it is the Law of action and its reaction.

Therefore, we can say that the Law of conservation of momentum is based on Newton's
Third Law of motion, and option (C) is correct.

Note: Newton's First Law of motion tells us that a body's motion does not change with time if a force does not act it.
From the second law concept, we can write force applied on a body is equal to the change of momentum' rate of that body.
The Law of gravitation tells us that if there are two bodies A and B separated by some distance, then there is a force of attraction between them, which is directly proportional to the mass of these bodies and the distance between their centers.
