Solution

The correct option is D Silver
Magnets can only be made out of magnetic materials. Materials attracted to a magnet, are called magnetic materials. Materials like steel, nickel, and cobalt, etc. are magnetic in nature. Hence, they can be magnetised easily. On the other hand, silver is a non-magnetic substance. Therefore, a magnet cannot be made from silver.
