Fact based on the reduction potential values.

The correct order will be

\mathrm{Cl}_{2} | \mathrm{Cl}^{\ominus}>\mathrm{Ag}^{+}|\mathrm{Ag}>\mathrm{I}_{2}|\mathrm{I}^{\ominus}>\mathrm{Na}^{\oplus } |\mathrm{Na}>\mathrm{Li}^{\oplus} | \mathrm{Li}

Thus, the given electrode couple can be arranged in order of their reduction potential values as

 \mathrm{A>C>B>D>E}

Hence, the correct answer is option(1)
