Inside the battery (we stress INSIDE the battery) in a closed circuit (consider the battery attached to a lightbulb with the light bulb glowing), the battery (a) creates positive charge. (b) pumps positive charge from its positive terminal to its negative terminal. (c) creates negative charge. (d) pumps positive charge from its negative terminal to its positive terminal. I think that batteries pump current (positive charge) from the positive terminal to the negative terminal, because if batteries work due to an electric field, then the positive current would have to move toward the negative terminal. So based on this I think the answer is B. But batteries produce electrostatic potential energy so doesn't that mean it would create positive charge (A) as well? So I guess I would go with B, but I'm really not sure.
