C Correct answer
Explanation

The Carnot cycle has the maximum theoretical efficiency among all heat engine cycles operating between the same two temperature limits, as stated by the Carnot theorem. Real cycles like Rankine, Brayton, and Otto have lower efficiencies due to irreversibilities, practical limitations, and finite heat transfer rates. The Carnot efficiency is given by 1 - T_cold/T_hot.
