________ is the most reliable test for magnetism.

Solution
The correct option is B Repulsion
Attraction can occur between unlike poles of two magnets as well as between a magnet and magnetic material. Therefore, the pieces that attract each other could be both magnets, or a magnet and a magnetic material. In case of magnets, repulsion occurs only between like poles. Therefore, repulsion is the most reliable test for magnetism.
