What is the normal oral temperature for a healthy individual?

The normal oral temperature for a healthy individual is generally recognized as 98.6 °F (37 °C). This value serves as a standard reference point in clinical practice and is based on the average body temperature measured orally in a resting state. It is important to note that body temperature can vary slightly among individuals due to factors such as time of day, activity level, and individual metabolism.

In the context of the provided options, this value is commonly accepted in medical references and is what healthcare professionals typically refer to when determining if a patient's temperature falls within the normal range. Variations around this average can be considered normal, but 98.6 °F remains the established benchmark for evaluating body temperature in a clinical setting.
