Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Work done depends on the change in potential energy. And since potential energy depends on just height of the inclined plane, work done is same regardless of slope.
Work done $= m g h = m g l s i n θ$ over inclined plane
