Fire Extinguisher Class B is designed for fires involving which substances?

Explanation:
Fire extinguishers are classified by the type of fuel they’re designed to handle. Class B is meant for fires that involve flammable liquids, such as gasoline, oil, solvents, and similar fuels. These liquids ignite and burn in a way that requires an extinguisher that can smother the flame and cool the liquid, rather than one that works on solids or electrical equipment. That’s why this choice fits best: it targets flammable liquids like gasoline and oil. It wouldn’t be appropriate for metal fires, electrical equipment fires, or ordinary combustibles like wood and paper, which are covered by other classes.
