(D) The fluoride ion $(F^-)$ has an atomic number of $9$. Since it has a charge of $-1$,the total number of electrons is $9 + 1 = 10$ electrons.Isoelectronic species are those that have the same number of electrons.For $Ne$ (atomic number $10$),the number of electrons is $10$.For $O^{2-}$ (atomic number $8$),the number of electrons is $8 + 2 = 10$.For $N^{3-}$ (atomic number $7$),the number of electrons is $7 + 3 = 10$.Since all the given species have $10$ electrons,they are all isoelectronic with the fluoride ion $(F^-)$.

Fluoride ion $(F^-)$ is isoelectronic with:
