Based on the properties of sodium chloride (NaCl) and carbon dioxide (CO2):
**A. NaCl is a formula unit that has a crystalline structure with repeating subunits and CO2 can exist as a single molecule.**
This statement is true.
NaCl is an ionic compound that forms a crystalline lattice structure made up of repeating units of Na^+ and Cl^-. On the other hand, CO2 is a molecular compound that exists as discrete molecules.
Therefore, the correct answer is **A**.
