Given the standard reduction potentials $$\mathrm{Sn^{4+}+2e^-
ightarrow Sn^{2+}}$$, $$0.15\ \mathrm V$$, $$\mathrm{Hg_2^{2+}+2e^-
ightarrow2Hg}$$, $$0.92\ \mathrm V$$, and $$\mathrm{PbO_2+4H^++2e^-
ightarrow Pb^{2+}+2H_2O}$$, $$1.45\ \mathrm V$$, which statement is true?

A

$$\mathrm{Sn^{2+}}$$ is a stronger oxidizing agent than $$\mathrm{Pb^{4+}}$$

B

$$\mathrm{Sn^{2+}}$$ is a stronger reducing agent than $$\mathrm{Hg_2^{2+}}$$

C

$$\mathrm{Hg^{2+}}$$ is a stronger oxidizing agent than $$\mathrm{Pb^{4+}}$$

D

$$\mathrm{Pb^{2+}}$$ is a stronger reducing agent than $$\mathrm{Sn^{2+}}$$
