Answer:
<h2>C. weight.</h2>
Explanation:
Inertia is defined as the ability of a body to continue its movement (or remain at rest) until an external force intervenes and changes its direction, speed and orientation. In other words, inertia is the resistance of changing the movement state.
In addition, when we talk about this resistance of changing the movement state, we must talk also about mass, because that intrinsic property is related with inertia. The more mass a body has, more difficult is to change its state, which means, that it has greater inertia. That's why the correct answer is weight, because weight is the force that the mass exercise inside a gravitational field, that is, the mass is directly proportional to weight, the more mass more weight, and at the end, more inertia.
