Solution

The correct option is C Zero
Work done = Force $*$ displacement i.e W = F.x Cos $θ$ where $θ$ is the displacement angle
W = F. Cos 90 = 0 (Since Cos 90 degree is equal to zero)
Hence when the force applied and displacement of the body are inclined at 90 degree's with each other work done is zero.
