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.
And, A geothermal heat pump operating at a COPheating of 3.5 provides 3.5 units of heat for each unit of energy consumed (i.e. 1 kWh consumed would provide 3.5 kWh of output heat). The output heat comes from both the heat source and 1 kWh of input energy, so the heat-source is cooled by 2.5 kWh, not 3.5 kWh.
