AI Explanation

The correct answer is C) C. A fire that starts in a switchboard due to a short circuit is considered a Class C fire. Class C fires involve energized electrical equipment, such as wiring, motors, and control panels. The key characteristic of a Class C fire is the presence of electricity, which can conduct the fire and make it dangerous to use water or other conductive extinguishing agents. The other answer choices are incorrect because: A) Class A fires involve ordinary combustible materials like wood, paper, and cloth; B) Class B fires involve flammable liquids and gases; and D) Class D fires involve combustible metals, which are not involved in an electrical fire.
