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