Solution

The correct option is C $M g$
$E_{M g_{2 +} / M g}^{0} = - 2.37$ V
$E_{F e_{2 +} / F e}^{0} = - 0.04$ V
As reduction potential of $F e^{2 +}$ is higher that that of $M g^{2 +}$
in term of oxidation potential
$E_{M g_{2 +} / M g}^{0} = 2.37$ $V$
$E_{F e_{2 +} / F e}^{0} = 0.04$ $V$
$⟹$ strong reducing agent reduce other species $⟹$ oxidise itself $⟹$ should have high oxidation potential. As $M g$ has high oidation potential than Fe.
$∴$ $M g$ will act as strong reducing agent.
