Normal body temperature in Celsius is approximately?

• A. 36 C
• B. 38 C
• C. 37 C
• D. 39 C

Answer: (C)

Normal body temperature is about 37°C, which serves as the reference point for a healthy adult. There's some natural variation, and the exact reading depends on how you measure it; oral temperatures are typically around 36.5–37.5°C, rectal readings tend to be a bit higher, and underarm readings a bit lower. A reading around 38°C or higher is usually considered a fever, signaling the body is fighting an illness or infection. A reading around 36°C sits at the lower end of the normal range and can occur in healthy individuals as well. With these ranges in mind, 37°C is the standard approximate normal value used in most contexts.
