Answer:
D. Opposite poles attract each other, while like poles repel each other.
Explanation:
Magnetic poles are the end regions of the magnet. There are two poles in a magnet. They are north and south poles. The magnetic field is the strongest in these poles. The pole of the magnet which points towards the north is termed as the north pole. The pole of the magnet which points towards the south is termed as the south pole. Two magnets facing each other with opposite poles attract each other. While two magnets facing the like poles, repel each other.
