What's the average body temperature?

Explanation:
Normal body temperature isn’t a single fixed value; it varies within a range due to time of day, activity, and how it’s measured. For healthy adults, the typical normal range is about 97°F to 100°F, with an average around 98.6°F. This spread reflects diurnal variation and individual differences, and it’s the range clinicians use to interpret what’s normal versus fever. The measurement method matters—oral temperatures are usually lower than core readings like rectal by a small amount—so knowing how you’re measuring helps place the number within that normal window. The other options either fall outside this usual spread or don’t capture the full range of normal variation.
