Solution

The correct option is D dsp2
[Ni(CN)4]2 is an square planar complex with dsp2 hybridization.
The outer electronic configuration of Ni2+ ion is 3d84s0
One 3d, one 4s and two 4p orbitals undergo dsp2 hybridization to give four equivalent dsp2 hybrid orbitals which are occupied by 4 electron pairs from 4 cyanide ligands.

This forms [Ni(CN)4]2
