Explanation:
To extinguish a grease fire in the kitchen involving animal fats and vegetable oils, you should use a Class B fire extinguisher. Class B extinguishers are designed for flammable liquid fires such as grease, oil, gasoline, and other chemicals. It's important to remember that water should never be used to put out a grease fire as it can cause the oil to splatter and spread the fire.
Class A extinguishers are intended for ordinary combustibles like wood and paper, Class C for electrical equipment, and Class D for flammable metals. In a kitchen fire involving oils and fats, a class K fire extinguisher, which is a special type of Class B extinguisher, is more suitable for restaurants and commercial kitchens. However, for the purposes of this question, the correct answer is b) Class B.
