The principle means of discharge for a carbon dioxide extinguisher is which of the following?

Explanation:
Stored pressure is how a carbon dioxide extinguisher discharges. The extinguishing agent is already under high pressure inside the cylinder, so when you open the valve, that pressure pushes the liquid CO2 out through the hose and nozzle. This immediate, pressurized release is essential for delivering CO2 effectively as a blanket over the fire. Other methods, like relying on gravity, or using a separate cartridge or a piston mechanism, aren’t how CO2 extinguishers are typically designed to operate, so they don’t provide the same reliable, rapid discharge.
