Final answer:
The core body temperature is the temperature at the center of the long bones of the limbs.
Step-by-step explanation:
The core body temperature refers to the internal temperature of the body, specifically the temperature at the center of the long bones of the limbs. It is not the average temperature across all portions of the body (option A), the average body temperature across all hours of the day (option B), or the temperature of the head and torso (option C).
Various sources mention that the average normal body temperature is around 36.5-37.5 °C (or 97.7-99.5 °F), but individual temperatures can vary within a small range. It's worth noting that the traditional average normal body temperature of 98.6 °F (37.0 °C) is not accurate for everyone.
