The correct answer is B, Class B. Class B fires involve flammable liquids and gases, including gasoline, oil, and solvents. When a fire occurs in the carburetor of a gasoline-powered service vehicle, it indicates the presence of flammable liquid—gasoline. Since gasoline is a flammable liquid, it falls under the Class B category.

In the context of fire classification, Class A fires involve ordinary combustibles such as wood, paper, and fabric, whereas Class C fires pertain to electrical equipment fires, and Class D fires involve combustible metals. These distinctions are important for determining the appropriate fire extinguisher to use and the appropriate response to each type of fire. Being aware that gasoline ignites easily and burns intensely is vital for ensuring safety and effectively dealing with such incidents.
