Which of the following temperatures is equal to 101° Fahrenheit?

To determine the equivalent temperature in Celsius for 101° Fahrenheit, it's important to apply the formula for conversion between these two temperature scales. The formula to convert Fahrenheit to Celsius is:

C = (F - 32) × 5/9

Plugging 101 into the formula:

C = (101 - 32) × 5/9

C = 69 × 5/9

C = 345/9

C = 38.3333...

This calculation shows that 101° Fahrenheit is approximately equal to 38.3° Celsius. The precision of 38.3° C reflects a common rounding in temperature conversion, which is why this answer is the most accurate match for the given Fahrenheit temperature.

The other temperature options, such as 69° C, 90° C, and 124.2° C, do not correlate with 101° F and are much higher than the calculated Celsius value. Therefore, it is clear that option A is the accurate choice for the temperature equal to 101° Fahrenheit.
