(C) The reducing power of a metal is inversely proportional to its standard reduction potential $(E^\circ)$.$A$ lower (more negative) $E^\circ$ value indicates a stronger reducing agent, while a higher (more positive) $E^\circ$ value indicates a weaker reducing agent.Comparing the given values:$E^\circ_{(	ext{Li}^+/	ext{Li})} = -3.05 	ext{ V}$$E^\circ_{(	ext{Mg}^{2+}/	ext{Mg})} = -2.36 	ext{ V}$$E^\circ_{(	ext{Ag}^+/	ext{Ag})} = 0.80 	ext{ V}$$E^\circ_{(	ext{Au}^{3+}/	ext{Au})} = 1.40 	ext{ V}$Since $	ext{Au}^{3+}/	ext{Au}$ has the highest positive standard reduction potential $(1.40 	ext{ V})$, it is the weakest reducing agent.

Which of the following metals behaves as the weakest reducing agent?
$E^\circ_{(\text{Li}^+/\text{Li})} = -3.05 \text{ V}$, $E^\circ_{(\text{Au}^{3+}/\text{Au})} = 1.40 \text{ V}$, $E^\circ_{(\text{Ag}^+/\text{Ag})} = 0.80 \text{ V}$, $E^\circ_{(\text{Mg}^{2+}/\text{Mg})} = -2.36 \text{ V}$
