પ્રક્રિયા $\frac{1}{2} H_{2(g)} + AgCl_{(s)} \rightleftharpoons H^{+}_{(aq)} + Cl^{-}_{(aq)} + Ag_{(s)}$ નીચેનામાંથી કયા ગેલ્વેનિક કોષમાં થાય છે?

• A
  $Pt \mid H_{2(g)} \mid KCl_{(aq)} \mid AgCl_{(s)} \mid Ag_{(s)}$
• B
  $Pt \mid H_{2(g)} \mid HCl_{(aq)} \mid AgCl_{(s)} \mid Ag_{(s)}$
• C
  $Ag_{(s)} \mid AgCl_{(s)} \mid KCl_{(aq)} \mid AgCl_{(s)} \mid Ag_{(s)}$
• D
  $Pt \mid H_{2(g)} \mid HCl_{(aq)} \mid AgNO_{3(aq)} \mid Ag_{(s)}$
