What range constitutes safe body temperature margins?

• A. 30-40 degrees Celsius
• B. 34.4-41.1 degrees Celsius
• C. 35-37 degrees Celsius
• D. 36-40 degrees Celsius

Answer: (B)

Body temperature is kept within a safety envelope where the body's processes can still function properly. Normal resting temperature sits around 37°C, with small natural fluctuations. The safe margins extend from about 34.4°C up to about 41.1°C. Dropping to 34.4°C or lower signals hypothermia with slowed metabolism and increasing risk to heart and organs; rising above 41.1°C raises the danger of hyperthermia and heat-related injury, including brain damage. So 34.4–41.1°C best captures the full safe range. The other options either go into dangerous low or high extremes or miss part of this envelope.
