Cell is behaving as galvanic when Eext < 1.1 V and as electrolytic when Eext>1.1 V

Q. A variable, opposite external potential ( $E_{e x t}$ ) is applied to the cell
$Z n ∣ ∣ (Z n)^{2 +} (1 M) ∣ ∣ (C u)^{2 +} (1 M) ∣ ∣ C u$ , of potential $1.1 V$ . When $E_{e x t} < 1.1 V$ and $E_{ext} > 1.1 V$ , respectively electrons flow from :

anode to cathode in both cases

anode to cathode and cathode to anode

cathode to anode in both cases

cathode to anode and anode to cathode

Cell is behaving as galvanic when $E_{e x t} < 1.1 V$ and as electrolytic when $E_{e x t} > 1.1 V$
