The appropriate portable extinguisher for extinguishing a fire in a computer is:

• A. Type A
• B. Type B
• C. Type C
• D. Type D

Answer: (C)

Fires in a computer involve energized electrical equipment, so the extinguisher used must be non-conductive and suitable for electrical fires. An extinguisher designed for electrical fires (often labeled for Class C) delivers a non-conductive agent such as CO2 or dry chemical, which can suppress the flames without risking electrical shock or conducting electricity back through the fire. Using extinguishers intended for ordinary combustibles or flammable liquids isn’t appropriate here and could spread the fire or cause harm. Similarly, fires involving metals require a different type of extinguisher, so they don’t fit this scenario.
