Which of the following CORRECTLY shows the relationship between Kelvin and Celsius?

A 0 Kelvin is -273 degrees Celsius.

explanation

Because Kelvin is an extension of the Celsius scale, an increase of 100 K results in an increase of 100 degrees C. For example:
-100 degrees C = 173 K
0 degrees C = 273 K
100 degrees C = 373 K, etc.
