Hi!
Magnets attract with opposite poles. The reason is the North pole of a magnet's magnetic lines (if that makes any sense) generally flow inwards, making it pulling in, and the South pole's magnetic lines flow outwards, pushing out. If you align two magnets with the same poles together, they will always repel, because they will be flowing in different directions.
However, if you align a north and a south pole together, they will work together, and attract.
Therefore, if you place two magnets randomly, and they're close enough, they'll align so that the north pole of one magnet faces the south pole of the other magnet, or choice A.
