Which three temperature readings all mean the same thing?

A). 100 Kelvin, 0 degrees Celsius, 32 degrees Fahrenheit

B). 273 Kelvin, 0 degrees Celsius, 212 degrees Fahrenheit

C). 373 Kelvin, 100 degrees Celsius, 212 degrees Fahrenheit

D). 273 Kelvin, 100 degrees Celsius, 212 degrees Fahrenheit

C). 373 Kelvin, 100 degrees Celsius, 212 degrees Fahrenheit

Explanation:

Kelvin and Celsius are related using the equation K = C + 273.

Celsius and Fahrenheit are related using the equation F = (9/5) * C + 32.

This means that Kelvin and Celsius have to differ by 273, in which only B and C fit that description.

Then you can look at the Celsius and Fahrenheit readings from B and C and apply the equation F = (9/5) * C + 32. For B, you take 0 degrees Celsius and substitute it in for C to get F = (9/5) * 0 + 32, in which you get 32 degrees Fahrenheit and not the 212 degrees in answer B. For C, you do the same: F = (9/5) * 100 degrees Celsius + 32 = 212 degrees Fahrenheit, which does agree with the answer. Therefore, it must only be C.
