None of the above

Detailed explanation-1: -Newton’s first law states that an object in motion tends to remain in motion with same speed and direction, or object at rest tends to be at rest, until and unless an external unbalanced force acts on the object. This tendency of an object to resist its initial state of motion is called inertia.
Detailed explanation-2: -Inertia: tendency of an object to resist changes in its velocity. An object at rest has zero velocity-and (in the absence of an unbalanced force) will remain with a zero velocity. Such an object will not change its state of motion (i.e., velocity) unless acted upon by an unbalanced force.
Detailed explanation-3: -Inertia is the resistance of any physical object to any change in its state of motion. This includes changes to the object’s speed, direction, or state of rest.Inertia is also defined as the tendency of objects to keep moving in a straight line at a constant velocity. examples of inertia of rest.
Detailed explanation-4: -Inertia can be defined as the tendency or ability of an object to resist change in motion.
