The operating temperature of cold storage is \(280^{\circ}\) \(\mathrm{k}\) and the heat leakage from the surroundings is \(35 \mathrm{kw}\) for the ambient temperature of \(310^{\circ} \mathrm{k}\). If the actual COP of the refrigeration plant is onefourth of an ideal plant working between the same temperature limits, the power required to drive the plant would be:

(a) \(3.7 \mathrm{kw}\)

(b) \(7.5 \mathrm{kw}\)

(c) \(12 \mathrm{kw}\)

(d) \(15 \mathrm{kw}\)
