Answer :
The best fire extinguisher to have in a kitchen where there is a greater risk for fires involving cooking oils and grease is c. a Class K extinguisher.
This is because Class K fire extinguishers are specifically designed to combat fires involving cooking oils, fats, and grease, which are common in kitchens. Using water on a grease fire is extremely dangerous as it can cause the fire to spread more rapidly.
Class A and Class B extinguishers are not suitable for kitchen grease fires. Class A extinguishers are meant for ordinary combustibles like wood and paper, and Class B extinguishers are designed for flammable liquids like gasoline or oil but not specifically for high-temperature cooking oils.
Class K extinguisher is equipped with a special wet chemical that cools the flames and forms a foam blanket to prevent re-ignition, making it the most effective tool for kitchen fire safety.
