In an air-standard Otto cycle, the compression ratio is 10. The condition at the beginning of the compression process is 100 kPa and 27 °C. Heat added at constant volume is 1500 kJ/kg, while 700 kJ/kg of heat is rejected during the other constant volume process in the cycle. The specific gas constant for air is 0.287 kJ/kg-K. The mean effective pressure (in kPa) of the cycle is:

A. 103
B. 310
C. 515
D. 1032
