Which chemical species can easily form an ionic bond with a cation?

sr

ne

nh4+

po43–

The correct option is PO43-.
PO43- [phosphate anion] is an anionic chemical specie which will readily react with a cation to form an ionic bond. The cation will donate three electrons to the phosphate anion thus removing the -3 negative charge; the phosphate anion will thus be transformed to a phosphate molecule.
