A 7 kilogram object at rest

Explanation:

The inertia of an object depends only on its mass. It is the measure of its mass only. The inertia of an object is independent of its speed. Mass is the amount of matter contained in it. A massive body have more inertia than a lighter body. As a result, a massive body requires larger force to stop as compared to a lighter body.

A 7 kilogram object is at rest has the greatest inertia. Hence, the correct option is (c) "A 7 kilogram object at rest ".
