The electrical conductivity of a solution depends on the total number of ions produced per molecule of the complex. The reference complex, $[A g (N H_{3})_{2}] N O_{3}$ , dissociates into 2 ions ( $[A g (N H_{3})_{2}]$ ⁺ and $N O_{3}$ ⁻). Here is how the options dissociate:

A) $[F e (e n)_{3}]_{2} (S O_{4})_{3}$ : Produces 5 ions ( $2 \times [F e (e n)_{3}]$ ³⁺ + $3 \times S O_{4}$ ²⁻).

B) $N a_{2} [PtC l_{6}]$ : Produces 3 ions ( $2 \times N a$ ⁺ + $[PtC l_{6}]$ ²⁻).

C) $K_{4} [F e (CN)_{6}]$ : Produces 5 ions ( $4 \times K$ ⁺ + $[F e (CN)_{6}]$ ⁴⁻).

D) $N a_{3} [A g (S_{2} O_{3})_{2}]$ : Produces 4 ions ( $3 \times N a$ ⁺ + $[A g (S_{2} O_{3})_{2}]$ ³⁻).

Since all options produce more ions than the reference, all of them (A, B, C, and D) exhibit higher electrical conductivity.
