Expert Answer
As the bulbs of decorative lights are connected in series if only one bulb will stop working or get disconnected all bulbs in the series will get affected as the circuit will not get completed. Thus even if 3rd light goes off of gets disconnected all the bulbs stop glowing.
Thus, Option (B) is correct.
