Option 2 : replace one cell with a piece of metal wire

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,

replace one cell with a piece of chalk - No conduction takes place
replace one cell with a piece of metal wire - One cell bulb (gets dimmer)
replace one bulb with a piece of metal wire cells cell one bulb gets (brighter)
replace one bulb with a cell - Three cells one bulb (Brighter)
