Option 2 : One bulb and two cells

Concept:

Power in a circuit is a product of the voltage and the current.
Its SI unit is the watt.
Mathematically, P= IV

Explanation:

If the bulb is connected in series circuits, the current will be the same in all the bulbs.
So, among the above-given options, a simple circuit with one bulb and two cells provides greater electricity, and thus the circuit having maximum output power will have the bulb which grows the brightest.

Thus, we can say that one bulb with two cells will glow brighter.
