If a fire involves ordinary combustibles, which class is it?

Explanation:
Fires are categorized by the fuel involved, which tells you the safest way to fight them. Ordinary combustibles such as wood, paper, cloth, and other everyday materials form Class A. The cooling effect of water-based extinguishers is especially suited to Class A because removing heat stops the combustion reaction. That’s why this option is the correct match. Other classes cover different fuels—flammable liquids, energized electrical equipment, and combustible metals—which require different extinguishing approaches.
