d) Class D fire extinguisher.
Explanation:
The type of fire extinguisher that should be used for fires involving pool chemicals is a Class D fire extinguisher. These are designed for fires caused by combustible metals, such as magnesium, titanium, and sodium, elements that often present in pool chemicals. Class A, B, and C fire extinguishers are not suitable for extinguishing such fires.
This is due to the different compositions of the extinguisher classes: Class A is meant for common combustibles like wood and paper, Class B is for flammable liquids and gasses, and Class C is for electrical fires.
