The correct option is A True
Attraction can occur in the case of two magnets (with opposite poles brought together) as well as between a magnet and a magnetic material such as iron. Therefore if both the pieces attract each other, they may be magnets or one may be a magnet and other may be a magnetic material.
Whereas, repulsion is possible only in case of two magnets (with same poles brought together). Therefore repulsion is a true test for magnetism.
