A class "B" fire involves

  1. Vegetable oils or fats

  2. Ordinary combustible materials

  3. Electrical equipment

  4. Flammable liquids

The correct answer is: Flammable liquids

Class "B" fires involve flammable or combustible liquids, gases and greases, such as gasoline, oil, and paints. These types of fires are particularly prevalent in environments where these substances are commonly stored or used, including many types of manufacturing and industrial settings as well as transportation. Flammable liquids can easily catch fire and spread rapidly, they can also re-ignite after the flames are initially extinguished making it more dangerous. In the context of fire classes, the other options mentioned in the question correspond to different classes. Class "A" fires involve ordinary combustible materials like wood or paper, class "C" fires involve electrical equipment, and class "K" fires involve vegetable oils or fats. But these are not related to class "B" fires, hence, they are not the right answer to the question. So class "B" fire is correctly associated with flammable liquids as per the fire classification.
