Answer 1

The correct option is A

Live wire

Explanation for correct option:

1. (a) Live wire
2. In any appliance, the current flow can be switched off using a switch.
3. The current flows through the live wire to the appliance.
4. So a switch in a circuit is always connected in the live wire.

Explanation for incorrect option:

1. (b) Earth wire: It grounds the excess current from the appliance. So it cannot be connected to switch.
2. (c) Neutral wire: It has main purpose of completing the electrical path back to the source, hence it cannot be connected to the switch.

Hence, The correct answer is Option (a) Live wire
