(D) Delocalisation occurs in species that exhibit resonance. In $H_2$,$HS^{-}$,and $CH_4$,the electrons are localised in sigma bonds. In the carbonate ion $(CO_3^{2-})$,the $\pi$ electrons are delocalised over the three oxygen atoms due to resonance,which is represented by the resonance hybrid structure.
