1. Type A

2. Type B

3. Type C

4. Type D

The correct answer is: Type B

The correct answer is Type B, which is specifically designed to combat fires involving flammable liquids such as gasoline, oil, and solvents. Type B fire extinguishers work by smothering the fire and cutting off its oxygen supply, as well as preventing the flames from spreading. They utilize agents such as foam, dry chemical powders, or carbon dioxide, which are effective against liquid fuel fires. Understanding fire extinguisher classifications is essential for safety in any environment where flammable materials are present, as each type is tailored to address specific fire risks effectively. Type A extinguishers tackle fires involving ordinary combustibles such as wood and paper, Type C is meant for electrical fires, and Type D is suitable for flammable metals. Each type has a unique purpose, emphasizing the importance of selecting the right extinguisher in emergency situations.
