Which temperature range represents normal body temperature?

Normal body temperature is generally recognized to hover around 98.6°F (37°C), but it can vary within a certain range depending on the individual and other factors. The correct answer provides a temperature range of 96-99.5°F (35.5-37.5°C), which encompasses the average body temperature's fluctuations due to factors like time of day, activity level, and individual metabolic differences.

This range effectively captures the lower and upper limits of what is considered normal, allowing for typical variations while still adhering to established clinical standards. In contrast, other choices may present ranges that either extend below or above what is generally accepted, indicating fevers or hypothermic conditions, which do not represent a healthy or normal physiological state. The inclusion of both Celsius and Fahrenheit scales in the correct choice demonstrates a comprehensive understanding of normal body temperature across different measurement systems.
