Answer:
Incomplete question but the closest ans is
A) The displacement is not zero
Explanation:
For work to be done, the direction of force has to be parallel to or in the same direction as the displacement, this can then be calculated by
θ
Where θ is the angle between direction of force and direction of displacement
By this equation,
if Force is zero, W is zero
if displacement is zero, W is zero
if force and displacement are perpendicular θ=90, cosθ = 0
So A is the cloest choices
