Verified by Experts

The correct Answer is:
D
In bulb 2, 3&4 current gets divided at 1&5 current adds up to give total value of current.
Also bulb which receives maximum current will glow more brighter, so it is clear that, Current in bulb 1&5 are maximum and resistance are same. So these bulbs glow with more brightness.
