ACO2
BFoam
CDry chemical
DAll of the above
AI Explanation
The correct answer is D) All of the above. All three fire extinguishing agents - CO2, foam, and dry chemical - can be used effectively to combat a class B fire, which is a fire involving flammable liquids and gases. These agents work by smothering the fire, interrupting the chemical reaction, or cooling the fuel source. This makes them suitable for extinguishing fires involving materials such as gasoline, oil, paint, and propane. The other options are incorrect because they do not cover all the effective agents for class B fires.
