Solution

The correct option is C Assertion is correct but Reason is incorrect
Assertion:
While pushing a body up a inclined plane the opposing forces are gravity + friction
But while pushing the same body down a inclined plane, it is only friction and also gravity is supporting force.
Friction is same in both the cases.
So it is true.
Reason:
The nature of friction is to resist relative motion between surfaces in contact. So it acts opposite to the direction of motion of body.
