Solution

The correct option is B
For an LED bulb to light-up in a circuit, the circuit must be closed. By closed circuit we mean that there is no breakage in the connecting wires and the switch is closed. Another condition for the bulb to glow is that is there must be an energy source like battery/cell in the circuit.
