Gas turbine engines and airbreathing jet engines use the Brayton Cycle. ... air and fuel mixture is then ignited in an expansion cylinder and energy is released, ... increase in the gas turbine inlet temperature for two different pressure ratio values. ... with thepressure ratio (thus the thermal efficiency) and the net work output.

The logical conclusion would be C
