The correct answer is C. Inertia.
Inertia is the inherent property of a body which offers reluctance to change its state of rest or uniform motion. It is a measure of how difficult it is to change the motion of an object. The more inertia an object has, the more difficult it is to accelerate or decelerate.
Weight is the force of gravity acting on an object. It is calculated by multiplying the mass of the object by the acceleration due to gravity. The acceleration due to gravity is a constant, so the weight of an object depends only on its mass.
Mass is a measure of how much matter is in an object. It is a fundamental property of matter, and it is not affected by gravity.
Momentum is a measure of the motion of an object. It is calculated by multiplying the mass of the object by its velocity. The velocity of an object is a vector quantity, so momentum has both magnitude and direction.
