Solution

The correct option is A $[A g (N H_{3})_{2}]^{+}, [A g (C N)_{2}]^{-}$ & $[A g (S_{2} O_{3})_{2}]^{3 -}$
Reactions of complex formation-

$A g^{+} N H_{3} - -- \to [A g (N H_{3})_{2}]^{+}$

AgCl dissolves in dilute ammonia solution to give the dimmine silver (l) ion:

All silver halide dissolve in thiosulphate and cyanide solutions giving thiosulphato and dicyano complexes of silver (l).

$A g^{+} C N^{-} - -- \to [A g (C N)_{2}]^{-}$ and

$A g^{+} (S_{2} O_{3})^{- 2} - ---- \to [A g (S_{2} O_{3})_{2}]^{- 3}$

Hence,option A is correct.
