Assertion:- Machine parts are jammed in winter.
Reason:-The viscosity of lubricant used in machine part decrease at low temperature.

View answer and explanation

Correct option: C

If Assertion is True but the Reason is False

The correct answer is C because the assertion is true (machine parts can jam in winter), but the reason is false (viscosity increases at low temperatures).
