the figure is the same as in question 9........but the ans is not option A because if we add a battery between the probes in the same order , then as overall , the negative terminal of the two batteries will come in contact and as we know both the batteries will push electricity against each other and we have to subtract its voltage , thus resulting in decrease in the amount of electricity or short circuit may happen.
