If the filament of bulb Q is fused then the circuit is not being completed because the electrons won't be able to reach the positive terminal as they would be stopped by the broken filament and electricity won't be able to pass through the filament to the negative terminal and due to the two cases that a circuit has to be completed for electricity to move and second one given it is proven that option 'B' is the correct option instead of 'A' 'C' or ' D'
