Answer 1

Answer:

The surest test of magnetism is c) Repulsion

Because it will prove if the magnets have magnetism or not. Sometimes, substances that do not have magnetism also may attract each other but won't repel at any cost. When we keep same sides of two magnets facing each other, such as N - N,
