Final answer:
Technician B is correct.

Technician B is correct. Electrical fires are extinguished with Class C fire extinguishers, not Class A fire extinguishers.
Gasoline fires, on the other hand, are extinguished with Class B fire extinguishers, as Technician B mentioned. Class B fire extinguishers are specifically designed to tackle flammable liquid fires such as gasoline.
