• B. Sneezing
• C. Chills
• D. Dry Mouth and Thirst

Answer: (A)

Exertional heat illness shows when the body’s cooling system is overwhelmed, with dizziness, plus signs of overheating such as heavy sweating (heat exhaustion) or hot, dry skin (heat stroke), often accompanied by nausea. The best immediate steps are to move the person to shade or a cooler environment, remove excess clothing, encourage fluids if they can drink, and start cooling with fans or ice packs (or cool water/ice bath) until medical help arrives. These actions directly address elevated core temperature and help prevent progression to a more dangerous state. Other signs like sneezing or only dry mouth and thirst don’t indicate an urgent overheating crisis and don’t guide the rapid cooling response in the same way. If any confusion, collapse, or loss of consciousness occurs, seek emergency care immediately.
