AI Explanation
The correct answer is D) All of the above. All three fire extinguishing agents - dry chemical, foam, and CO2 - can be used to effectively combat a Class B fire, which involves flammable liquids and gases. Dry chemical extinguishers smother the fire, foam creates a barrier to cut off oxygen, and CO2 displaces oxygen to extinguish the flames. These agents are all approved and commonly used for Class B fire suppression on vessels, in accordance with Coast Guard regulations.
