I agree with omkar,maitri,abhid etc all who are saying option B because we can read that another bulb 'Z' is connected in "PARALLEL" and not in "SERIES" and as we know , if we connect many bulb with same battery in a parallel circuit , they will give same brightness if the one bulb was connected , but the consumption of battery will also increase.So, according to me , there will be no change in bulb y (NORMAL)ans should be : option "A"

I think (A) is the answer because the explanation in the solution makes complete sense but technically it could also be (B)
Ans 9:

The correct answer is B as the bulb Y is in straight series and there is no change of current passing through it. And the curent gets equally divided among X and Y.
Ans 13:
Class : Class 9
correct answer should be option B because there is no change in the current passing through lamp Y.
