Now that I think about it, Baelor is right. The question did not give a diagram, and the answer only said the magnet was “close” or “near” the other magnet, however it did not define how the position was laid out. Only in a certain position when the two magnets with coils were both in line with each other (kind of hard to explain), basically in a specific layout, would turning on and off the current induce anything on the other coil. Thus I believe the correct answer was only III, which was putting a magnet through a coil or something like that.
