AIIMS 2019 Physics Refrigeration Assertion Reason Question

Option B is correct because both the assertion and reason are true: the Coefficient of Performance (COP) can indeed be less than or greater than one, depending on the specific conditions of the refrigeration cycle. However, the reason provided does not directly explain the assertion; while it accurately describes the function of a refrigerator, it does not clarify why the COP can vary. Option A is incorrect because the reason is not a correct explanation of the assertion. Option C is incorrect as both statements are true, and option D is incorrect because both statements are factual. Understanding that COP is a measure of efficiency in heat transfer processes helps clarify these concepts.
