Strategy: Identify isostructural pairs of molecules/ions using VSEPR calculations.
Step 1: VSEPR Analysis Count valence electrons and electron pairs for each species in the options. Species with the same hybridization and same number of lone pairs on the central atom are isostructural.
Step 2: Selection The pair identified as having the same shape (e.g., and ) is the answer.
