(C) The central metal ion is $Ni^{2+}$,which has an electronic configuration of $[Ar] 3d^8$.$CN^-$ is a strong field ligand,which causes the pairing of electrons in the $3d$ orbitals.After pairing,the configuration becomes $d^8$ with no unpaired electrons,leading to $dsp^2$ hybridization.This results in a square planar geometry and diamagnetic behavior due to the absence of unpaired electrons.
