Solution
The correct option is D Electric iron
An essential electric component in a household wiring system is one without which the system would fail.
So, components like live, neutral, and earth wires, electric sockets, miniature circuit breaker (MCB) or electric fuse, must be present in a household electrical system.
However, an electric iron is an appliance that is optional in a household. It is not an essential component to have in a domestic electric circuit.
