The correct answer is:
**d. He does work as he picks up the box and as he lifts it to the shelf.**
In physics, work is done when a force is applied to an object, and the object moves in the direction of that force. Aidan does work when he lifts the box from the floor and when he places it onto the shelf. Although he carries the box across the room, if he is moving horizontally and not applying vertical force (like lifting), there is no work done on the box in the direction of the force of gravity during that segment.
**d. He does work as he picks up the box and as he lifts it to the shelf.**
