Which one of the following is correct relation between (COP)HP and (CO...
Explanation:

Given Relation: (COP)HP - (COP)R = 1
This relation indicates the difference between the Coefficient of Performance (COP) of a heat pump (HP) and a refrigerator (R) is equal to 1.
Let's break down the relation for better understanding:
- (COP)HP: Coefficient of Performance of a Heat Pump
- (COP)R: Coefficient of Performance of a Refrigerator
Here, the COP of a heat pump is always greater than the COP of a refrigerator because a heat pump is used for heating purposes, while a refrigerator is used for cooling purposes. Therefore, the difference between the COP of a heat pump and a refrigerator is 1.
Hence, the correct relation is:

(COP)HP - (COP)R = 1
