Which of the following fire types is correctly matched with its classification?

When classifying fires, different types of combustible materials determine the appropriate classification scheme. The classifications are generally assigned letters, with each letter corresponding to specific fire hazards.

A Computer Fire is typically classified as a Class C fire, which involves electrical equipment and components. This classification is important because water is not safe to use on such fires due to the risk of electrical shock, and specialized extinguishers are required.

A Trash Fire is generally considered a Class A fire. Class A fires involve ordinary combustibles such as wood, paper, cloth, and some plastics. These materials are typically easier to manage with water-based extinguishing methods.

Magnesium Fires are classified as Class D fires because they involve combustible metals. Class D fires require specific extinguishing agents that are effective for metal fires, as traditional methods like water or foam can exacerbate the fire.

Finally, Gasoline Fires fall under Class B fires since they involve flammable liquids and vapors. Class B fires require extinguishing agents that can smother the fuel, preventing it from igniting.

Thus, the matching provided in the chosen answer accurately reflects the classifications of these fire types, correctly associating them with their respective categories.
