Best answer
Correct Answer - Option 4 : C

Explanation:

  • All the electric appliances stop working in a house when the main switch is put off because the electric circuit (the path where the electricity travels) gets opened.
  • A circuit needs to be closed in order for current to flow through it and thus all electric appliances to work.
  • On switching off the mains switch of the house, live and neutral wires are disconnected in order to break the circuit.
