JEE Main Chemistry question

**Statement 1:** The cell potential of the mercury cell is 1.35 V, which remains constant throughout its life.

**Statement 2:** In the mercury cell, the electrolyte is a paste of KOH and ZnO.

(A)Statement 1 is True, Statement 2 is True; Statement 2 is a correct explanation for Statement 1
(B)Statement 1 is True, Statement 2 is True; Statement 2 is not a correct explanation for Statement 1Correct
