Question

The reaction

$\frac{1}{2} \mathrm{H}_{2}(\mathrm{~g})+\mathrm{AgCl}(\mathrm{s}) \rightleftharpoons \mathrm{H}^{+}(\mathrm{aq})+\mathrm{Cl}^{-}(\mathrm{aq})+\mathrm{Ag}(\mathrm{s})$

occurs in which of the given galvanic cell.

$\mathrm{Ag}|\mathrm{AgCl}(\mathrm{s})| \mathrm{KCl}\left(\mathrm{sol}^{\mathrm{n}}\right)\left|\mathrm{AgNO}_{3}\right| \mathrm{Ag}$

$\mathrm{Pt}\left|\mathrm{H}_{2}(\mathrm{~g})\right| \mathrm{HCl}\left(\mathrm{sol}^{\mathrm{n}}\right)|\mathrm{AgCl}(\mathrm{s})| \mathrm{Ag}$

$\mathrm{Pt}\left|\mathrm{H}_{2}(\mathrm{~g})\right| \mathrm{HCl}\left(\mathrm{sol}^{\mathrm{n}}\right)\left|\mathrm{AgNO}_{3}\left(\mathrm{sol}^{\mathrm{n}}\right)\right| \mathrm{Ag}$

$\mathrm{Pt}\left|\mathrm{H}_{2}(\mathrm{~g})\right| \mathrm{KCl}\left(\mathrm{sol}^{\mathrm{n}}\right)|\mathrm{AgCl}(\mathrm{s})| \mathrm{Ag}$
