Apull pin, open valve, and pull up on release lever
Bpull pin and open valve
Copen valve, pull pin, and pull up on release lever
Dopen valve and pull pin
AI Explanation

The correct answer is B) pull pin and open valve. The reason this is the correct answer is that this type of carbon dioxide (CO2) fire extinguisher is designed to be operated by first pulling the pin, which releases the safety mechanism, and then opening the valve to discharge the CO2 agent. This is the standard procedure for operating a CO2 extinguisher with this type of head design, as specified in fire safety regulations and training. The other answer choices are incorrect because they either include additional unnecessary steps (A and C) or omit the critical step of pulling the pin (D), which is required to release the safety mechanism and allow the extinguisher to discharge properly.
