The C.O.P. of a refrigerator working on a reversed Carnot cycle is (where T1 = Lowest absolute temperature and T2 = Highest absolute temperature)

Answer: Option A

The C.O.P. of a refrigerator working on a reversed Carnot cycle is $$\frac{{\text{T}}_1}{{\text{T}}_2-{\text{T}}_1}$$
Where
T₁ = Lowest absolute temperature,
T₂ = Highest absolute temperature
