You Have Just Put Fresh Batteries in Your Flashlight and It

You have just put fresh batteries in your flashlight and it is working nicely. Now suppose that you remove one of the batteries and reinsert it backward. Despite the fact that the one battery is reversed, both batteries connect properly to one another and to the flashlight, so that there are no connection problems in the flashlight. As the result of this battery reversal, the flashlight will

A) work in reverse, lighting up when you put its switch in the "off" position and not lighting up when you put its switch in the "on" position.
B) remain lit regardless of the position of its on-off switch.
C) not light up at all, regardless of the position of its on-off switch.
D) work normally, lighting when you switch it "on" and turning off when you switch it "off."
