(A) The hybridization and bond angles for the given species are:$BeCl_{4}^{2-}: sp^{3}$ hybridization,bond angle $\approx 109^{\circ} 28'$$BeCl_{3}^{-}: sp^{2}$ hybridization,bond angle $\approx 120^{\circ}$$BeCl_{2}: sp$ hybridization,bond angle $= 180^{\circ}$Comparing the bond angles:$BeCl_{4}^{2-} (109^{\circ} 28') \rightarrow BeCl_{3}^{-} (120^{\circ})$: Bond angle increases.$BeCl_{3}^{-} (120^{\circ}) \rightarrow BeCl_{2} (180^{\circ})$: Bond angle increases.$BeCl_{2} (180^{\circ}) \rightarrow BeCl_{4}^{2-} (109^{\circ} 28')$: Bond angle decreases.Thus,the correct diagram shows an increase from $BeCl_{4}^{2-}$ to $BeCl_{3}^{-}$,an increase from $BeCl_{3}^{-}$ to $BeCl_{2}$,and a decrease from $BeCl_{2}$ to $BeCl_{4}^{2-}$. This corresponds to the diagram in option $A$.
