Solution

The correct option is C $0 J o u l e$
The work done is $0$ in this case.
Ram is carrying the weight of the bag which is being applied in the vertical direction and the bag is being displaced in the horizontal direction. So there is no force in the direction of displacement. As work done is product of force and displacement, the value will be zero as the force in the direction of displacement is zero.
