Solution

The correct option is D $Z n$ reduces $F e^{2 +}$
The one with the higher $S R P$ value is easiest to reduce for a cell.
$E_{c e l l} = S R P_{o x i d a n t} - S R P_{r e d u c t a n t}$
$∵ S R P$ of $Z n < S R P$ of $F e$
$∴$ $Z n$ reduces $F e^{2 +}$

Option D is correct.

$E_{c e l l} = S R P_{o x i d a n t} - S R P_{r e d u c t a n t}$
$∵ S R P$ of $Z n < S R P$ of $F e$
$∴$ $Z n$ reduces $F e^{2 +}$

Option D is correct.
