The reduction potential of Fe is very high, so it is a strongest reducing agent.

Q. Which one among the following is the strongest reducing agent?
$F e^{2 +} + 2 e^{-} \to F e (- 0.44 V)$
$N i^{2 +} + 2 e^{-} \to N i (- 0.25 V)$
$S n^{2 +} + 2 e^{-} \to Sn (- 0.14 V)$
$F e^{3 +} + e^{-} \to F e^{2 +} (+ 0.77 V)$

$F e$

$F e^{2 +}$

$N i$

$S n$

The reduction potential of $F e$ is very high, so it is a strongest reducing agent.
