Rankine Cycle Operating on Low Pressure Limit of P1 and High

Rankine cycle operating on low pressure limit of p1 and high pressure limit of p2

A) has higher thermal efficiency than the carnot cycle operating between same pressure limits
B) has lower thermal efficiency than carnot cycle operating between same pressure limits
C) has same thermal efficiency as carnot cycle operating between same pressure limits
D) may be more or less depending upon the magnitudes of p1 and p2
