Solution

Among the triatomic molecules/ions, $B e C l_{2}, {N_{3}}^{-}, N_{2} O, N O_{2}^{+}, O_{3}, S C l_{2}, {I C l_{2}}^{-}, {I_{3}}^{-}$ and $X e F_{2},$ the total number of linear molecule(s)/ion(s) where the hybridization of the central atom does not have contribution from the d-orbital(s) is 4.
These include $B e C l_{2}, {N_{3}}^{-}, N_{2} O, N O_{2}^{+}$ .
In the remaining molecules/ions, $O_{3}$ is bent, $S C l_{2}$ is V shaped with $s p^{3}$ hybridization, ${I C l_{2}}^{-}, {I_{3}}^{-}$ and $X e F_{2},$ are linear with $s p^{3} d$ hybridization.
