Which Celsius reading would clearly indicate fever according to the threshold?

• A. 37 C
• B. 36 C
• C. 39 C
• D. 35 C

Answer: (C)

Fever is defined as a body temperature above 38°C. Reading 39°C clearly crosses that threshold, so it indicates fever. A normal range is around 36.5–37.5°C, so 37°C is not fever, 36°C is below normal, and 35°C is too low. Hence, 39°C is the reading that meets the fever criterion.
