Correct option is C

The correct answer is (c) Inertia
· The mass of an object is the measure of its Inertia. Inertia is the resistance of an object to changes in its state of motion. An object with greater mass has more inertia and requires a greater force to accelerate it.
Details on other options:
· Volume: Volume refers to the amount of space occupied by an object. Mass is independent of the object's size or shape, though these can influence volume.
· Density: Density is the mass per unit volume of an object. It relates mass and volume, but mass itself is not the same as density.
· Force: Force is an interaction that can cause an object to change its motion. While mass and force are related through Newton's second law (F = ma), mass itself is not a force.
