Which of the following does not contain coordinate covalent bond ?

In ${\mathrm{CH}}_3^{-}$ion, carbon atom does not have lone pair of electrons. Carbon, C atom has octet number of electrons of its valency shell. Hence, there is no coordination covalent bond present in  ${\mathrm{CH}}_3^{-}$ ion.

But in the remaining three cases, at least one lone pair of electrons to be present at the central atom or ligand $\left({\mathrm{CN}}^{-}\right)$
