Solution

The correct option is A Steel spoon
A conductor of electricity is a material which allows an electric current to flow through it. Glass, rubber and plastic are examples of insulators. But steel is a conducting material.

Since, a steel spoon is a conductor of electricity, current will pass through it. So, Avinash can use a steel spoon to complete the circuit.
