AClass "A"
BClass "B"
CClass "C"
DClass "D"
AI Explanation
The correct answer is B) Class "B" fire. Diesel oil is a flammable liquid fuel, and fires involving flammable liquids are classified as Class "B" fires according to the fire classification system used for US Coast Guard Captain's License Examinations. Class "B" fires are those that involve flammable liquids, gases, and greases, which require a smothering effect or an oxygen-excluding agent to extinguish them. Burning diesel oil would not be considered a Class "A" (ordinary combustible), Class "C" (energized electrical equipment), or Class "D" (combustible metals) fire.
