The coefficient of performance of a Carnot refrigerator working between TH and TC is K and the efficiency of a Carnot engine working between the same TH and TC is η. Then
(A) ηk = \(\frac{Q_H}{Q_C}\)
(B) \(\frac{η}{k}\) = \(\frac{Q_C}{Q_H}\)
(C) \(\frac{η}{k}\) = \(\frac{Q_H}{Q_C}\)
(D) ηk = \(\frac{Q_C}{Q_H}\)
