**Category:** Inorganic Chemistry  
**Subtype:** Identification of Substances  
**Problem Description:** Identify the solid form of a substance that sublimates instead of melting, commonly used for creating cold and dry environments for food preservation.  

**Answer Options:**  
A. Solid \(\mathrm{H}_{2} \mathrm{O}\) (ice)  
B. Solid \(\mathrm{SO}_{2}\) (solid sulfur dioxide)  
C. Solid \(\mathrm{CO}_{2}\) (dry ice)  
D. Solid CO (solid carbon monoxide)  

**Key Concept:** The problem is about recognizing the correct chemical compound that is referred to as "dry ice," which sublimates directly from solid to gas without melting.
