If  \[A{{g}^{+}}+2N{{H}_{3}}\rightleftharpoons {{\left[ Ag{{(N{{H}_{3}})}_{2}} \right]}^{+}};{{K}_{1}}=1.7\times {{10}^{7}}\]\[;A{{g}^{+}}+C{{l}^{-}}\rightleftharpoons AgCl\,\,;{{K}_{2}}=5.4\times {{10}^{9}}\] Then for \[AgCl+2N{{H}_{3}}\rightleftharpoons {{[Ag{{(N{{H}_{3}})}_{2}}]}^{+}}+C{{l}^{-}}\]; equilibrium constant will be

A)  \[0.31\text{ }\times {{10}^{-2}}\]

B)  \[3.2\text{ }\times {{10}^{2}}\]

C)  \[9.18\text{ }\times \text{ }{{10}^{16}}\]        

D)  \[1.00\text{ }\times \text{ }{{10}^{-17}}\]
