Concept:Inertia is the property of matter that opposes any change in its state of rest or uniform motion.
Explanation:A body at rest tends to stay at rest unless a net external force acts on it.
When a force is applied, the body resists the change because of its inertia.
This resistance is not a force itself; it is a passive property of the body.
The greater the mass of the body, the greater its inertia.
Therefore, the tendency of a body to remain at rest when a force is applied is called inertia.
Friction is a contact force, momentum is mass in motion, and impulse is a change in momentum.
Answer:Inertia (Option C).
