Answer 2

The more inertia that an object has, the more mass that it has and the greater tendency it has to resist changes in its state of motion.

Answer: Option A

Explanation:

Inertia is defined as the resistance offered by a body or an object to change in its state of motion, by an external force. An external agent cannot disturb a body, until it has more magnitude than its normal force.

Normal force is nothing but due to the mass of the body, being in contact with the ground. So, inertia is purely dependent on the mass of the body. The unit of inertia is ‘kg’. Hence, more mass gives more amount of inertia.
