AWater fog
BDry chemical
CFoam
DCO2
AI Explanation
The correct answer is D) CO2. CO2 is the best extinguishing agent for electrical fires because it is a non-conductive gas that effectively smothers the fire by displacing oxygen, without causing damage to the electrical equipment. Water, foam, and dry chemical agents can all conduct electricity, increasing the risk of electric shock and potential damage to the equipment. CO2 is the safest and most effective option for extinguishing electrical fires, as per Coast Guard regulations.
