Solution

The correct option is D [Ni(CO)4], [Ni(CN)4]2are diamegenetic[Ni(Cl)4]2
is paramegenetic


As CO and CN are strong ligand so they form low spin complex and pairing happens so they are diamagnetic but Cl is a weak ligand so it higher spin outer orbital complex and in this complex Ni has 2 unpaired electron so it is paramagnetic.

Hence,option C is correct.
