Solution
The correct option is A Soft iron
An electric bell is a mechanical or electronic bell that functions by means of an electromagnet. When an electric current is applied, it produces a repetitive buzzing, clanging or ringing sound.
The material used for making the armature of an electric bell is soft iron which can induce magnetism rapidly.Hence it can serve as a good electromagnet.
