C

D
Apply mechanical foam.
AI Explanation
The correct answer is B) Shut off the source of the gas feeding the fire. For a liquefied gas fire, the preferable way to extinguish it is to shut off the source of the gas that is feeding the fire. This is because liquefied gases, such as propane or natural gas, can reignite if the source of the gas is not stopped. Applying water, foam, or dry chemical extinguishers may temporarily extinguish the visible flames, but the fire will likely re-ignite as long as the gas source is still feeding the fire. Shutting off the gas source is the most effective way to completely extinguish a liquefied gas fire and prevent reignition.
