A block of mass m is slowly carried on a inclined plane by a force F which always acts along the tangent to the plane. If the co-efficient of friction between the block and incline be `mu`, then work done by force of friction while carrying block from bottom of the plane to the top will be `:`

A

dependent on the actual shape of the path between point A and B.

B

will have a total positive value

C

will not change if force F is not applied along the tangent to the plane always.

D

independent of the actual shape of the path between points A and B.
