Question: 1 / 400

What begins to set in after thirty minutes or more of immersion in cold water?

Frostbite

Hypothermia

Prolonged immersion in cold water can lead to hypothermia, a dangerous drop in body temperature. Frostbite typically develops after prolonged exposure to cold, but it is the freezing of body parts due to direct contact with extreme cold, not overall body temperature drop. Immersion foot, also known as trench foot, is a condition that occurs when the feet are exposed to damp and cold conditions for an extended period of time. Heat stroke is caused by prolonged exposure to high temperatures, and is not relevant to the question. Therefore, the correct answer is B, hypothermia.
