The correct answer is A) Type A. Type A fires are characterized by the burning of ordinary combustible materials, such as wood, paper, cloth, and plastics. The quenching and cooling effects of large quantities of water or water-based solutions are the most effective methods for extinguishing Type A fires. The other options are incorrect because: B) Type B fires involve flammable liquids and gases, which require different extinguishing agents like dry chemical or carbon dioxide. C) Type C fires involve energized electrical equipment, which require non-conductive extinguishing agents like CO2 or dry chemical. D) Type D fires involve combustible metals, which require specialized extinguishing agents specific to the metal involved.
