Solution

The correct options are
A $d^{2} s p^{3}$ hybridisation state
C Paramagnetic
$C N^{-}$ is a strong field ligand that will cause the pairing of the electrons in the 3d orbital. Therefore, it undergoes $d^{2} s p^{3}$ hybridization and 1 electron in the 3d orbitals remain unpaired. Hence, it is paramagnetic in nature.
