Solution
The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Coefficient of performance (COP), is an expression of the efficiency of a heat pump.
The coefficient of performance or COP (sometimes CP or CoP) of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work required. Higher COPs equate to lower operating costs. The COP usually exceeds 1, especially in heat pumps, because, instead of just converting work to heat (which, if 100% efficient, would be a COP_hp of 1), it pumps additional heat from a heat source to where the heat is required.
