Answer:

Circuit A

Step-by-step explanation:

Let voltage of one battery be V

The circuit at the top has an overall voltage of
V

Circuit A is in series which means the overall voltage is
V+V=2V

Circuit B is the same as Circuit C where both are parallel to the bulb.

The overall voltage is
(1)/(V)+ (1)/(V) = (2)/(V)

Circuit D will not work as the negative terminal of the battery are touching one another thus it impedes the electron flow in the circuit
