Class B fire involves which fuel?

Explanation:
Class B fires are defined by the fuel being flammable liquids. Fuels like gasoline, solvents, paints, and other liquids burn easily and can release vapors that spread the fire, so the focus is on liquids rather than solids, gases, or electrical equipment. The other options point to different fire types: solids would be Class A, live electrical equipment is handled separately due to electrical hazards, and flammable gases are a different category because gas behavior changes how the fire needs to be managed. Halon is a suppressant that’s effective on liquid fires, but the key idea is that the fuel involved is a flammable liquid.
