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.

Other suitable extinguishing agents for electrical fires include Carbon Dioxide (CO₂) extinguishers and Halon or Halocarbon agents (though some are restricted due to environmental concerns). The classification of fires (A, B, C, D, K, or E) helps determine the appropriate extinguishing agent. Electrical fires are commonly referred to as Class C in the US and Class E in Europe/Australia, referring to energized electrical equipment.
