detailed solution

Correct option is Y

When a resistance of R is connected in parallel between B and C.

The effective resistance between B and C will be RBC=50.R50+R

So the potential difference between B and C is given by VRBCRBC+RAB, which is given as 1003V

RBCRBC+RAB=13

on solving we get R=50Ω
