Coefficient Of Performance (COP) is the ratio of "Coldness" produced to the "Heat" or " Work" supplied. In the case of a vapor compression system, it is the mechanical or electrical work, which is the Input to the machine. Since, "work" is considered as High-Grade energy, the conversion of "work" into other forms of energy, the process is more efficient, and the COP is mostly greater than 1

Coefficient of Performance of Domestic Refrigerator
The coefficient of performance (COP) of a domestic refrigerator is the ratio of the heat removed from the refrigerated compartment to the energy consumed by the compressor. It is a measure of the efficiency of the refrigerator.
COP = Heat Removed / Energy Consumed
COP > 1
A COP greater than 1 indicates that the refrigerator is more efficient at removing heat than the energy consumed by the compressor. This means that the refrigerator is able to remove heat from the refrigerated compartment while consuming less energy.
Domestic refrigerators are designed to have COP greater than 1, which makes them energy efficient. The higher the COP, the more efficient the refrigerator is at removing heat.
The COP of a refrigerator can be improved by using a better compressor, better insulation, and other design improvements.
Conclusion
Therefore, the correct answer is option 'B', which states that the coefficient of performance of a domestic refrigerator is more than 1.
