Answer & Explanation
The correct answer is Option B: B) Replacing the propellant cartridge and refilling it with powder.
For cartridge-operated extinguishers, the propellant charge (cartridge) and the fire-extinguishing powder are stored separately. After discharge, the cartridge must be replaced and the vessel must be refilled with the specified amount of powder to ensure it functions correctly.
