Explanation:

To solve this, we recall the definitions of the terms: a bond is a force holding atoms together, a molecule is a group of atoms bonded together, and an atom is the smallest unit of matter. So the correct term to fill in the blank is "atom" as it matches the description of the smallest unit of matter.

Answer:

The missing word is "atom", so we drag "atom" into the blank. The correct option is the one with "atom".
