Final answer:
The normal range of human body temperature is generally considered to be from 36.5°C to 37.5°C. Given the options, 36.5-37.2°C falls within this range and is the most accurate answer provided.
Step-by-step explanation:
The question pertains to the normal range of human body temperature. Based on the provided information, the average normal body temperature is considered to be 37.0°C. Variations in this temperature could indicate different medical conditions.
Option (a) mentioned as 'pituitary; 36.5-37.5 °C' aligns with the general understanding of normal human body temperature range, suggesting that the correct temperature range in this context is 36.5-37.5°C. The range of 36.5-37.2°C given in the options is narrower but still within the normal range. Hence, if we are to choose among the provided options, 1) 36.5-37.2 would be most accurate as it is part of the commonly accepted range for body temperature.
