answer should be d because in 1 and 2, direction of stroking is from right to left and thus, where the pole of the magnet is north and south, they will at the same place on the steel bar. in option 3, where the pole of the magnet is north/south, but on the steel bar it is the opposite(south/north). but because the direction is not left to right, but right to left, thus, all the options are correct.
