What is the normal body temperature?

• A. 98.6 F
• B. 97.0 F
• C. 99.9 F
• D. 100.4 F

Answer: (A)

Normal body temperature is about 98.6°F. This classic value serves as the standard reference for a healthy adult, though normal can vary slightly from person to person and through the day. Temperature readings depend on where you measure it (oral, rectal, ear, or underarm) and can be a bit higher or lower in different situations. While the typical oral normal range is roughly 97.8–99.1°F, 98.6°F is the widely used benchmark. Readings around 99–100°F are often checked for fever, especially if sustained. So, 98.6°F is the best answer for the standard normal temperature.
