Select pair of compounds in which both have different hybridisation but have same molecular geometry.

Both ${\mathrm{ICl}}_2^{-}$ and ${\mathrm{BeCl}}_2$ are linear but ${\mathrm{ICl}}_2^{-}$ has ${\mathrm{sp}}^3\mathrm{d}$and ${\mathrm{BeCl}}_2$ has sp hybridization. ${\mathrm{ICl}}_2^{-}$ has a structure with 5 electron pairs. Its hybridization is hence ${\mathrm{sp}}^3\mathrm{d}$. The linear structure is due to the fact that of those 5 electron pairs, 2 are bond pairs and 3 are lone pairs. As ${\mathrm{BeCl}}_2$ Its structure is linear and contains sp hybridization.
