Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Angle of repose is equal to the angle of friction as both of them are calculated corresponding to the limiting friction.
Definition of limiting friction provided in the question is correct, but it is not an explanation to the assertion.
Hence, option B is correct.
