Why does Carnot cycle has maximum efficiency?
A. Since all the processes in Carnot cycle are completely reversible
B. Since only process of expansion and compression are reversible
C. Since only the process of heat addition and heat rejection are reversible
D. Since all processes involved are irreversible
