Solution

The correct option is D The cell reactions are represented as $A^{2 +} + 2 e^{-} \to A$ and $B \to B^{2 +} + 2 e^{-}$ .
Cell diagram is represented as
$A_{(s)} A n o d e ∣ ∣ ∣ {A^{+ 2} O x i d a t i o n}_{(a q)} ∣ ∣ ∣ ∣ ∣ ∣ ∣ B_{(a q)}^{+ 2} C a t h o d e ∣ ∣ ∣ ∣ {B R e d u c t i o n}_{(s)}$ .
The cell reactions are represented as $A \to A^{+ 2} + 2 e^{-}$ and $B^{+ 2} + 2 e^{-} \to B$
