Answer: (B)

The acronym PASS is a critical mnemonic for the correct operation of a fire extinguisher, standing for Pull, Aim, Squeeze, and Sweep. Each component of PASS plays an essential role in effectively extinguishing a fire.

Firstly, "Pull" refers to removing the safety pin from the handle of the extinguisher. This action is crucial as it allows the extinguisher to be activated. Without pulling the pin, the extinguisher remains locked and cannot discharge the extinguishing agent.

Next, "Aim" instructs the user to direct the nozzle at the base of the fire. This is important because targeting the base of the flames is necessary for extinguishing the fire effectively. Hitting the flames or the smoke above the fire will not have the desired effect, as the source of combustion must be addressed.

Then, "Squeeze" indicates the action of squeezing the handle to release the extinguishing agent. This step ensures that the extinguishing material is actively discharged toward the fire, enabling it to suppress the flames.

Finally, "Sweep" involves moving the nozzle from side to side while aiming at the base of the fire. This sweeping motion helps to cover the area in a systematic manner, ensuring that the fire is adequately extinguished and
