Assertion(A): AC current is used in wheat stone bridge arrangement to measure conductivity of ionic solution.
Reason (R): If DC current is used in wheat stone bridge arrangement, it will lead to electrolys is of the solution taken in the cell. So AC current is used to prevent electrolysis.

(b) Both A and R are wrong
(c) A is correct but R is wrong
(d) A is wrong but R is correct
