Boojho and Paheli performed experiments taking similar bulbs and cells but two different solutions A and B as shown in figure. They found that the bulb in the setup A glows more brightly as compared to that of the setup B. You would conclude that

A higher current is flowing through the circuit in setup A.
B higher current is flowing through the circuit in setup B.
C equal current is flowing through both the circuits.
D the current flowing through the circuits in the two setups cannot be compared in this manner.


the answer would not be A, but rather C as same types of cells were used, but the solution may be a weaker or stronger conductor of electricity
