Burn injuries come from damage to tissue caused by heat transfer, and they are commonly categorized as thermal burns (from hot objects or liquids), chemical burns (from caustic substances), or electrical burns (from current passing through tissue). Frostbite, by contrast, is tissue injury caused by freezing temperatures that damages cells and blood vessels due to cold exposure. It isn’t driven by heat damage, so it isn’t classified as a burn—even though it can resemble one in appearance. So the frostbite choice isn’t a burn, making it the correct answer.
