Assertion $A:$ In equation $\Delta_r G =- nFE _{\text {cell }}$ value of $\Delta_r G$ depends on $n$.
Reasons $R$ : $E_{\text {cell }}$ 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
