Answer: "A1 and B1 are like poles, but there is not enough information to tell whether they are north poles or south poles."

Reason: like poles repel and unlike poles attract. Because A1 and B1 repel, they must have the same polarity, but the experiment doesn't tell which polarity (north or south) that is.
