The reaction \[\tfrac{1}{2}{{H}_{2}}(g)+AgCl(s)\,\to \,{{H}^{+}}(aq)+C{{l}^{-}}(aq)+Ag(s)\]                 occurs in the galvanic cell                                                 [IIT 1985; AMU 2002; KCET 2003]

A.                 \[Ag/AgCl(s)\,KCl\,(\text{soln})\,\,||\,\,AgN{{O}_{3}}\,(\text{soln})\,/Ag\]
B.                 \[Pt/{{H}_{2}}(g)\,HCl\,(\text{soln})\,\,||\,\,AgN{{O}_{3}}\,(\text{soln})\,/Ag\]
C.                 \[Pt/{{H}_{2}}(g)\,HCl\,(\text{soln})\,\,||\,\,AgCl\,(s)\,/Ag\]
D.                 \[Pt/{{H}_{2}}(g)\,KCl\,(\text{soln})\,\,||\,\,AgCl\,(s)\,/Ag\]
Answer» D.                 \[Pt/{{H}_{2}}(g)\,KCl\,(\text{soln})\,\,||\,\,AgCl\,(s)\,/Ag\]
