Which outcome occurs when inefficiencies reduce a Carnot engine's cycle?

A)Entropy increases in each cycle✓

B)Net work output approaches maximum

C)Isothermal expansion approaches irreversibility

D)Adiabatic compression becomes more reversible

💡 Explanation

Entropy increases because inefficiencies introduce irreversibilities in the cycle via increased friction and heat loss; therefore, entropy generation grows above zero each cycle, rather than being ideally constant at zero for reversible idealized cycles.
