Answer:

flat, so that the north pole of the magnets on the train point up and the north poles of the magnets on the track point down

Explanation:

Remember that when dealing with magnetism opposites are attracted to eachother and similar are repelled so if you want the maglev train to float, you´d need equal poles facing eachtoher in order to be repelled from one another, so the only option that actually is creating a repellent force upward for the train against the track would be the option B.
