The standard reduction potentials at \( 25^{\circ} \mathrm{C} \) of \( \mathrm{Li}^{+} \mid \mathrm{Li} \), \( \mathrm{Ba}^{2+}\left|\mathrm{Ba}, \mathrm{Na}^{+}\right| \mathrm{Na} \) and \( \mathrm{Mg}^{2+} \mid \mathrm{Mg} \) are \( -3.05,-2.73,- \) \( 2.71 \) and \( -2.37 \mathrm{~V} \), respectively. Which is the strongest reducing agent?
(A) \( \mathrm{Li} \)
(B) \( \mathrm{Ba} \)
(C) \( \mathrm{Na} \)
(D) \( \mathrm{Mg} \)
