Answer
A
the number of atoms given in a formula unit.
B
many molecules that are represented by the formula unit.
C
many atoms that are arranged in a regular pattern.

A crystal consists of many atoms arranged in an orderly, repeating pattern. A formula unit gives the simplest ratio of particles in some substances; it does not mean the whole crystal contains just that number of atoms. Therefore, the correct choice is “many atoms that are arranged in a regular pattern.”
