Answer :
Final answer:
The fire extinguisher suitable for use on combustible liquids and fats, mentioned in the question, is a Class B fire extinguisher. The correct option is B.
Explanation:
The fire extinguisher described in the question that is used on oil, gasoline, paint, burning liquids, and cooking fats and contains graphite-type chemicals and carbon dioxide is a Class B fire extinguisher. Class B fire extinguishers are formulated to combat combustible liquid fires, which can involve fuel oil, paint, solvents, and grease. The graphite-type chemicals help to form a barrier that smothers the fire and prevents re-ignition.
The carbon dioxide effectively displaces oxygen, hindering the fire's ability to continue burning. Class B fire extinguishers are specifically designed to combat fires involving flammable liquids such as oil, gasoline, paint, burning liquids, and cooking fats. They contain graphite-type chemicals and carbon dioxide, which are effective in suppressing fires caused by these substances.
