AI Explanation
The correct answer is A) Flammable liquids, greases, etc., where a blanketing effect is essential. A Type B fire refers to a fire involving flammable liquids, such as fuels, oils, and greases. For these types of fires, a blanketing effect is essential to smother the fire and prevent it from reigniting. Extinguishing agents that create a smothering or blanketing effect, such as foam or dry chemical, are the most effective for Type B fires. The other options are not the most appropriate for this type of fire. Option B is for electrical fires, Option C is for metal fires, and Option D is for ordinary combustible materials fires, which require different extinguishing methods.
