Which behavior characterizes a poorly designed cryogenic refrigerator using a reversed Carnot cycle?

💡 Explanation

Irreversible heat transfer greatly diminishes cycle efficiency because the second law dictates maximum efficiency with reversible operation; therefore, option A, rather than reaching the Carnot limit, dominates, as irreversibility lowers the coefficient of performance.
