\mathrm{\left [ {Ag}\left(\mathrm{H}_{2} \mathrm{O}\right)_{2} \right ]\left [ {Ag}(\mathrm{CN})_{2}\right ]\rightarrow \left [ Ag \left ( H_{2}O \right )_{2} \right ]^{+}+\left [ Ag\left ( CN \right )_{2} \right ]^{-}}

                                                        \downarrow                                  \downarrow

                                                 Cation complex                  Anion complex

Cation Complex \Rightarrow Metal name : Silver

Anion Complex \Rightarrow Metal name  ( Suffix-ate or Latin names )           

                       \Rightarrow Argentate ( Latin name of Ag )

\mathrm{H}_{2} \mathrm{O} \rightarrow aqua , 2\left(\mathrm{H}_{2} \mathrm{O}\right) \rightarrow diaqua

\mathrm{CN}^{-} \rightarrow cyanide , 2\left(\mathrm{CN}^{-}\right) \rightarrow dicyanido

Oxidation state of  \mathrm{Ag=+1}

So IUPAC Name : Diaquasilver (I) dicyanidoargentate (I)

Hence correct option is 3
