Slide wire bridge is most sensitive when the resistance of all the four arms of bridge is same. Hence, B is the most accurate answer.

Q. R1​,R2​,R3​ different values of R, A, B, C are the null points obtained corresponding to R1​,R2​ and R3​ respectively. For which resistor, the value of X will be the most accurate and why?

Slide wire bridge is most sensitive when the resistance of all the four arms of bridge is same. Hence, B is the most accurate answer.

Q. $R_{1}, R_{2}, R_{3}$ different values of R, A, B, C are the null points obtained corresponding to $R_{1}, R_{2}$ and $R_{3}$ respectively. For which resistor, the value of X will be the most accurate and why?

Slide wire bridge is most sensitive when the resistance of all the four arms of bridge is same.
Hence, B is the most accurate answer.
