An example of a Class D fire would involve which type of material?

Explanation:
Class D fires involve burning metals such as magnesium, titanium, sodium, or potassium. These metals burn at very high temperatures and can react violently with water, so they require specialized extinguishing media—typically a dry powder designed for metal fires or smothering with inert material like sand—rather than water, foam, or CO2. Among the options, only flammable metals describe a material that fits this class, because wood is an ordinary combustible (Class A), gases correspond to other fuel/gas classifications, and electrical equipment fires fall under the electrical-class category. This is why metal fires need metal-specific extinguishing agents.
