A) Electromagnets cause a maglev train to levitate above the track through the principle of magnetic repulsion. In a maglev system, there are magnets (which can be electromagnets) in the track and corresponding magnets in the bottom of the train. When the magnets in the track and the magnets in the train are configured to repel each other, they create a force that lifts the train off the track, allowing it to levitate. This is achieved through the principle of magnetic repulsion.
So, the correct answer is: **Magnets in the track and magnets in the bottom of the train repel each other.**
