What is the normal body temperature range in Fahrenheit?

• A. 96.0-98.0
• B. 97.6-99.6
• C. 99.0-101.0
• D. 98.2-100.2

Answer: (B)

The key idea here is how normal body temperature varies and what range is considered typical for oral readings. Body temperature is tightly regulated by the hypothalamus, but it is not a single fixed number; it fluctuates with time of day, activity, and individual differences. For a standard oral measurement, the normal range is about 97.6 to 99.6°F. This window centers near the common average and accommodates normal diurnal variations, while staying well below the fever threshold (around 100.4°F) and above hypothermia ranges. The other ranges either miss the lower end of normal or extend toward values that could be interpreted as fever in many people, so they’re less accurate as the normal range.
