The correct answer is: $E_{\text {cell }}$ in the intensive property while $\Delta_r G$ of cell reaction is an extensive property.
$E_{\text {cell }}$ is intensive while $\Delta_r G$ is extensive. (In the relation, $\Delta G=-n F E, E$ depends only on the nature of the cell reaction so it is intensive whereas value of $\Delta G$ depends upon the value of $n$. So it is extensive.)
