• B. c and d
• C. a and b
• D. b and d

Answer 1

The correct option is A b and c

$C{O}_2$ extinguishers contain carbon dioxide, a non-flammable gas, and are highly pressurized. On grease fires, electrical fires - the flames will spread and make the fire bigger. Water extinguishers are filled with water and are typically pressurized with air. Electrical fires are fires involving potentially energized electrical equipment. These fires can be a severe hazard to fire fighters using water or other conductive agents, as electricity may be conducted from the fire, through water, to the firefighter's body, and then earth. Electrical shocks have caused many firefighter deaths. Thus, water extinguisher should not use for electrical fire.
