Explanation:

Dry ice is the common name for solid carbon dioxide ($\text{CO}_2$). Unlike regular ice (frozen water), dry ice does not melt into a liquid; instead, it sublimes directly from a solid to a gas at standard atmospheric pressure and a temperature of $-78.5 \text{ °C}$ ($-109.3 \text{ °F}$). This property makes it useful for refrigeration where a liquid residue is undesirable. Option A (Water in solid state) is regular ice. Option B (Water in gaseous state) is steam or water vapor. Option C (CO$_{2}$ in liquid state) refers to liquid carbon dioxide, which exists under high pressure, not typically as 'dry ice'. Therefore, dry ice is specifically carbon dioxide in its solid state.
