Answer:
A or B depending on your precision
Explanation:
In real life, applying to solid will shrink it depending on the amount of pressure applied, but due to the strength of solid bonds, the volume change is often negligible in practical situation and would only be accounted under astronomically high pressure phenomena (eg. at Jupiter's core or near black hole).
In high school level, and for many applications, it is entirely viable to completely neglect the change in solid volume under pressure. Thus, A is a legitimate answer. However, bear in mind that <em>in theory</em> the volume still decreases by a very slight amount. So B is correct as well, theoretically. The most correct option depends on the precision you needed.

Explanation:
Force may be defined as the cause of motion and deformation. When a force is applied to an object, the object either moves or changes shape or both. In most cases, it is not possible to detect the deformation by naked eyes at the molecular or atomic level. Deformation occurs no matter how small.
For example, a car moving along a straight and horizontal highway, experiences an engine force Fe, while being opposed by an overall frictional force, Ff ( road friction as well as air resistance). If the car is moving to the right and to the right is taken to be the positive direction, then Fe acts to the right and Ff acts to the left. The net force is ΣF = Fe - Ff .
