The question is incomplete, the complete question is:

What happens as a result of the kinetic energy of the particles in a liquid being comparable with the intermolecular attractions between the particles? A The particles do not move enough to change positions, so the liquid is not compressible. B The particles move enough that they separate from one another and take the shape of their container. C The particles do not move enough, so they are fixed in place, and the liquid has a fixed volume. D The particles move enough that they are not fixed in place, and the liquid can flow.

Answer:

The particles do not move enough to change positions, so the liquid is not compressible.

Explanation:

Intermolecular forces are the secondary bond forces that hold the particles of a substance together in a particular state of matter. In the liquid state, many times, it is observed that the kinetic energy of the particles is comparable to the degree of intermolecular attractions between particles. This has obvious implications for the liquid.

First of all, the kinetic energy of the liquid particles is significantly reduced such a that the particles do not move too much or translate. Hence the liquid will have a fixed volume and is also incompressible.
