Normal body temperature is approximately which value?

Normal body temperature is approximately which value?

• A. 99 F
• B. 98.6 F or 37 C
• C. 96 F
• D. 104 F

Answer: (B)

Normal body temperature tends to cluster around 98.6°F (37°C) in a healthy adult. This value has long served as the standard reference point, though in real life the normal range is about 97.8–99.1°F (36.5–37.3°C) and can vary with time of day, activity, and how temperature is measured (oral, rectal, ear, or underarm). Among the options, 98.6°F is the classic average that aligns with the standard 37°C benchmark. A reading around 99°F is still common and within normal variation, 96°F is considered low, and 104°F suggests fever or overheating. So 98.6°F (37°C) best represents the typical normal value.
