4. D

The correct answer is: A:B:C

The choice of the fire extinguisher that can be used on burning wood, paper, and cloth is a Class A fire extinguisher. This type is specifically designed to combat fires involving ordinary combustibles such as wood, paper, cloth, and some plastics. The classification system for fire extinguishers is structured to help users quickly identify which type of extinguisher to use for specific types of fires. A Class A extinguisher typically contains water or a foam agent that cools the burning materials and smothers the flames. In contrast, Class B extinguishers are intended for flammable liquids like gasoline or oils, while Class C extinguishers are designed for electrical fires. Class D extinguishers are meant for combustible metals and would not be suitable for a fire involving common household materials. Understanding this classification is crucial for effective and safe firefighting in various scenarios.
