Which one of the following complexes will consume more equivalents of aqueous solution of $\mathrm{Ag}\left({\mathrm{NO}}_3\right)$?${\mathrm{AgNO}}^3$

The anion ${\mathrm{Cl}}^{-}$ outside the coordination sphere gets precipitated with ${\mathrm{AgNO}}_3$. In the choice d, there are three chloride ions and thus will consume more equivalents of aqueous solution of ${\mathrm{AgNO}}_3$.
