Assertion :The heat rejected to the hot sink is greater than the heat absorbed from the cold source, so the heating COP is one greater than the cooling COP. Reason: CoP of a heat engine can be increased by decreasing its work input.

Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
The COP of a heat pump depends on its duty. The heat rejected to the hot sink is greater than the heat absorbed from the cold source, so the heating COP is 1 greater than the cooling COP.
The COP of a heat pump system can be improved by reducing the temperature gap $T_{h o t}$ minus $T_{c o l d}$ at which the system works.
