The best statement to describe particles of a liquid is:

Particles in a liquid are close together but can move around each other.

Here's why:

* Close together: Liquids have a definite volume because the particles are packed relatively close to each other. This is unlike gases, where particles are far apart.

* Move around each other: Liquids can flow because the particles are not locked in a rigid structure like solids. They have enough energy to move around and past each other.
