Answer 2

When the displacement produced in a body is perpendicular to the direction of applied force then work done is (b) Zero Joule.

No work is said to be done when the force is perpendicular to the displacement example when you push a wall, the wall does not move, here no work is done. Only when there is a change in the position of the object it is considered as work done.
