Solution
The correct option is D Cell
A cell converts stored chemical energy into electrical energy. It makes current to flow from the positive terminal to the negative terminal via an external circuit. An additional cell in the circuit will provide more electrical energy, which will make the bulb glow more brightly.
The additional cell should be connected in the circuit like the above figure, i.e., positive terminal of one cell should be connected with the negative terminal of another cell.
