Answer 2

Answer:

4) Both the end of B is repelled by the South Pole of a magnet.

Explanation:

If B is a bar magnet, then one end of B will be repelled by the south pole, namely B's south pole. However, B's north pole will be attracted towards the south pole of the bar magnet. Again, both ends being repelled cannot happen.
