What is the Celsius threshold corresponding to the heat index limit mentioned?

• A. 39 C
• B. 40 C
• C. 41 C
• D. 42 C

Answer: (C)

The heat index is how hot it feels to our bodies, combining the actual air temperature with humidity. In many safety guidelines, the limit is stated in Fahrenheit, commonly 105 °F. To compare with Celsius values, you convert that limit: 105 °F is about 40.6 °C, which is typically rounded to 41 °C. So the Celsius threshold that matches that limit is 41 °C. The other numbers would correspond to slightly lower or higher perceived heat, but 41 °C best aligns with the standard 105 °F limit used in guidance.
