Which Celsius value is listed as a normal body temperature?

• A. 35 C
• B. 37 C
• C. 36 C
• D. 38 C

Answer: (B)

Normal body temperature is kept at a tight level by the body's thermostat in the brain, so there’s a small window of what’s considered normal. In clinical practice, about 37°C is the standard reference value for a normal core temperature, with only small day-to-day or site-to-site variations. For example, oral measurements are typically around 36.5°C to 37.5°C, while core measurements can be a bit higher or lower depending on time of day and activity. So 37°C is the value most clearly listed as normal. A reading around 35°C would suggest hypothermia, and 38°C indicates fever. A value like 36°C can be normal in some contexts, but 37°C is the conventional baseline used as the standard normal reference.
