Yes even I agree with Shourya, answer is A. SOF why are you not giving solution for this test? There is no solution for any question

Ans 7:

Aarnav Grover from Anand Niketan Shilaj, Ahmedabad

It should be C because the ratio of A is that 1 bulb is getting 2 sources, meaning it is 1:2 while in C the ratio is 2:3, and 2 third is bigger than 1 half
