$A$ depolarizer used in dry cell batteries is

The correct formula of calomel is:

Given below are two statements: one is labelled as Assertion $A$ and the other is labelled as Reason $R$.
Assertion $A$: In equation $\Delta_r G = -nFE_{\text{cell}}$,the value of $\Delta_r G$ depends on $n$.
Reason $R$: $E_{\text{cell}}$ is an intensive property and $\Delta_r G$ is an extensive property.
In the light of the above statements,choose the correct answer from the options given below:

Which one of the following is the correct plot of $\Lambda_m$ (in $S \ cm^2 \ mol^{-1}$) and $\sqrt{C}$ (in $mol^{1/2} \ L^{-1/2}$) for a $KCl$ solution? ($y=\Lambda_m$; $x=\sqrt{C}$)
