Which type of portable fire extinguishers is NOT designed for use on flammable liquid fires?

AI Explanation
The correct answer is C) Water (cartridge-operated). Water-based fire extinguishers are not suitable for use on flammable liquid fires, as water can spread the fire and cause the burning liquid to splash. Dry chemical, foam, and carbon dioxide extinguishers are the appropriate types for fighting flammable liquid fires, as they smother the fire and prevent reignition. Water extinguishers are primarily designed for Class A (ordinary combustible) fires, not Class B (flammable liquid) fires. This is a key requirement in the US Coast Guard regulations for firefighting equipment on vessels.
