Given below are two statements
Statement –I : ${\left[Ni{\left(Cl\right)}_4\right]}^{2-}$ is tetrahydral & diamagnetic Complex with $ds{p}^2$ hybridization for Ni, but ${\left[Ni{\left(CN\right)}_4\right]}^{2-}$  is square planar, paramagnetic complex with $ds{p}^2$ hybridization for Ni, but $\left[Ni{\left(CO\right)}_4^{ }\right]$ is tetrahydral & diamagnetic complex with $ds{p}^2$ hybridization for Ni
Statement –II :  ${\left[NiC{l}_4\right]}^{2-},\left[Ni{\left(CO\right)}_4\right],{\left[Ni{\left(CN\right)}_4\right]}^{2-}$ have same d-electron configuration  have same geometry  and are paramagnetic.
