In a polytropic process, heat rejected is given by

• A. \(\frac{\gamma}{\gamma - 1} \times\) work done on the system
• B. \(\frac{\gamma - n}{\gamma - 1} \times\) work done on the system.
• C. \(\frac{\gamma - n}{\gamma} \times\) work done on the system
• D. \(\frac{\gamma - n}{\eta} \times\) work done on the system.
