Which of the following is NOT a type of fire extinguisher?

C. Foamite is not a standard type of fire extinguisher recognized by fire safety authorities. The conventional fire extinguishers include:

• Wet chemical extinguishers, primarily used for fires involving cooking oils and fats.
• Water extinguishers, effective on solid combustibles like wood and paper.
• Air pressurized water extinguishers, utilized for similar types of fires, providing a jet of water under pressure.
