Solution

The correct option is C permanent magnet
A permanent magnet has small sets of domains inside them. The orientation of different domains in a permanent magnet is always the same. If a permanent magnet loses this orientation of domains, it loses its magnetism. A metal or a non-metal may or may not have a singular orientation of domains.
