The correct answer is B. When a bar magnet is cut in half, each half has a north pole and a south pole.

So, Candice learned that every magnet has two magnetic poles. This means that when you cut a whole magnet into two parts, you will get two new magnets. According to her observation, each of these two new magnets are going to have a north pole and a south pole.
