Answer 2

(a) Diamagnetic

Explanation:

Since the material is repelled by the powerful magnet, it could be a diamagnetic substance because an applied magnetic field creates an induced magnetic field in them in the opposite direction, causing a repulsive force.

In contrast, paramagnetic and ferromagnetic materials are attracted by a magnetic field. A non-magnetic field is neither attracted nor repelled.

So Option A is the right choice.
