The correct answer is B) Dry chemical powder extinguisher.
Fires involving electrical equipment (often classified as Class E or Class C fires) require an extinguishing agent that is non-conductive. Water-based extinguishers (like pressurized water or foam, which is largely water) are conductive and can pose a severe electrocution risk to the user when used on electrical fires. Dry chemical powder extinguishers (like ABC powder) use fine powder that smothers the fire and also works on Class A, B, and C fires, making them suitable and common for electrical fires.
