Given below are two statements : Statement I: Ni CN 4 2 - is square planar and diamagnetic complex, with dsp 2 hybridization for Ni but Ni CO 4 is tetrahedral, paramagnetic and with sp 3 hybridication

Question

Given below are two statements :

Statement I: ${[Ni {(CN)}_{4}]}^{2 -}$ is square planar and diamagnetic complex, with ${dsp}^{2}$ hybridization for $Ni$ but $[Ni {(CO)}_{4}]$ is tetrahedral, paramagnetic and with ${sp}^{3}$ hybridication for $Ni$ .

Statement II : ${[{NiCl}_{4}]}^{2 -}$ and $[Ni {(CO)}_{4}]$ both have same d-electron configuration, have same geometry and are paramagnetic.

In light the above statements, choose the correct answer form the options given below
