(D) Isoelectronic species are those that have the same number of electrons.For $BF_3$: Total electrons = $5 + (3 	imes 9) = 5 + 27 = 32$ electrons.For $NO_3^-$: Total electrons = $7 + (3 	imes 8) + 1 = 7 + 24 + 1 = 32$ electrons.For $CO_3^{2-}$: Total electrons = $6 + (3 	imes 8) + 2 = 6 + 24 + 2 = 32$ electrons.For $BO_3^{3-}$: Total electrons = $5 + (3 	imes 8) + 3 = 5 + 24 + 3 = 32$ electrons.Since all the given species have $32$ electrons,they are all isoelectronic with $BF_3$.
