Answer-Which of the following is the position of the box K?

Box G was placed three boxes above box H which is neither placed at stack Z nor in the same stack as box G. Box I was placed two boxes above box H in the same stack. Box D was placed two boxes above box F and immediately below box L, which is placed to the west of box J. Box K was not placed at the bottommost position. Hence, case 2 gets eliminated.
