Answer:

2nd one

3rd and 4th circuits are not complete and in the 1st one wires connected to each bulb are connected to the same terminal of the battery. So there is no potential difference between the 2 ends of wire so the bulbs don't light up. For it to be correct one end of wire should be connected to positive terminal and the other one to the negative terminal
