A Class B fire involves?

Explanation:
Fires are categorized by what’s burning. Class B fires involve flammable liquids such as gasoline, solvents, and oils. That’s why flammable liquids are the correct choice: they form the fuel source for these fires, and the extinguishing approach focuses on separating the fuel from the flame with agents like foam, dry chemical powder, or CO2. Water is usually not the right choice because it can spread the liquid and worsen the flames. This differs from fires involving ordinary combustibles like wood or paper (Class A), electrical equipment (Class C), or metals (Class D).
