Step-by-step explanation:
The battery of setup 'a' is the strongest, this is indicated by the glowing of the bulb, as we can see the bulb is the brightest at the setup 'a'. Next moving on to the setup 'b', in this setup, the bulb is glowing a bit dimmer than the setup 'a', hence we can find out that setup 'b' battery strength is a little less than 'a'. Now coming to setup 'c', here we see that the bulb is not even glowing which indicates that the battery has no strength or that it has been used up.
