Solution

The correct option is B
25 J

Work done = Force x Displacement in the direction of the force
Work is the product of the force acting on the body and its displacement, so here displacement is 5 m as it is the distance in the direction of force applied to the box between two points. Hence work done by the force = 5 x 5 = 25 J.
