Kelvin is the absolute temperature scale that corresponds to which of the following?

Correct Answer: Option A — Absolute reading of a measured temperature in degrees Celsius.

The Kelvin scale is the SI unit for absolute temperature, where zero Kelvin represents the theoretical point of zero molecular motion. It is directly related to the Celsius scale by an offset of 273.15 degrees, making it the standard for thermodynamic calculations in gas turbine performance analysis.
