Gaseous carbon dioxide is represented by the molecules of \[\text{C}{{\text{O}}_{2}}\] . Therefore, option (c) is correct.

Work Step by Step

The chemical reaction for the sublimation of dry ice is \[\text{C}{{\text{O}}_{2}}(\text{s}) \to \text{C}{{\text{O}}_{2}}(\text{g})\] Sublimation is a physical change, so the composition of dry ice will remain the same. Option (c) represents the molecules of \[\text{C}{{\text{O}}_{2}}\] so it is the best representation.
