Given below are two statements : Statement I : $\displaystyle \left[\mathrm{Ni}(\mathrm{CN})_4\right]^{2-}$ is square planar and diamagnetic complex, with $\displaystyle \mathrm{dsp}^2$ hybridization for Ni but $\displaystyle \left[\mathrm{Ni}(\mathrm{CO})_4\right]$ is tetrahedral, paramagnetic and with $\displaystyle \mathrm{sp}^3$ - hybridication for Ni . Statement II : $\displaystyle \left[\mathrm{NiCl}_4\right]^{2-}$ and $\displaystyle \left[\mathrm{Ni}(\mathrm{CO})_4\right]$ 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:
