The correct answer is option c: They do work as they pick up the canoe and as they lift it to the top rack. Work is done when a force is applied and the object moves through a distance. The boys are exerting a force on the canoe to lift it and are moving it through a distance as they carry it across the yard and place it on the top rack. Therefore, work is being done during these actions.
