The correct option is D Battery, switch and conducting wire
An electric circuit consists of:
1. Source of electricity: Battery or cell delivers electricity in the circuit
2. Conducting wire: It provides the path of the circuit on which current flows
3. Switch: It is used to break or complete the circuit. Switch in ‘ON’ position completes the circuit and switch in ‘OFF’ position breaks the circuit (stops the flow of current in the circuit).
Hence, the battery, conducting wire and switch are used to make an electric circuit.
