B
Correct answer
Explanation
Normal human body temperature is approximately 37°C (98.6°F), though it can vary slightly throughout the day and from person to person. 36.9°C is within the normal range. 81.1°C is lethally hot (well above boiling), 21.7°C is dangerously cold (hypothermia range), and 98.6°C is body temperature in Fahrenheit, not Celsius.
