The correct range for a normal oral temperature in adults is typically considered to be between 97.6°F and 99.6°F. This range reflects the average body temperature, acknowledging natural variations due to factors such as individual metabolism, the time of day, and recent physical activity.

Consequently, option C accurately captures the established boundaries of normalcy in body temperature, which is crucial for health monitoring and assessment in a clinical setting.
