Answer: (C)

The transportation hazard class for flammable solids is classified as Class 4. This classification encompasses materials that can ignite spontaneously, burn when exposed to air, or are otherwise flammable. Class 4 is further divided into three divisions: Division 4.1 includes flammable solids, Division 4.2 covers spontaneously combustible materials, and Division 4.3 pertains to dangerous when wet materials.

Understanding why flammable solids are placed in Class 4 is important for ensuring appropriate handling and transportation measures to mitigate risks associated with potential ignition. This classification is essential for safety protocols and regulatory compliance in transporting hazardous materials.
