In which of the following structures coordination number for cations and anions in the packed structure will be same

The ratio of coordination numbers of ${\mathrm{Na}}^{+}$and ${\mathrm{Cl}}^{-}$ in $\mathrm{NaCl}$ is $1:1$i.e., same coordination no. for both ${\mathrm{Na}}^{+}$and ${\mathrm{Cl}}^{-}$.

The ratio of coordination numbers of ${\mathrm{Ca}}^{2+}$and ${\mathrm{F}}^{-}$in ${\mathrm{CaF}}_2$ is 2:1 i.e. different coordination no. for  ${\mathrm{Ca}}^{2+}$and ${\mathrm{F}}^{-}$.

The ratio of coordination number of ${\mathrm{Na}}^{+}$and ${\mathrm{O}}^{-2}$ in ${\mathrm{Na}}_2\mathrm{O}$ is $1:2$ i.e., different coordination no. for ${\mathrm{Na}}^{+}$and ${\mathrm{O}}^{-2}$.

The ratio of coordination number of ${\mathrm{Zn}}^{2+}$and ${\mathrm{S}}^{-2}$ in $\mathrm{ZnS}$ is $1:1$i.e., same coordination no. for both ${\mathrm{Zn}}^{2+}$and ${\mathrm{S}}^{-2}$.
