Which of the following cobalt-$(III)$ complex is paramagnetic and high spin complex?

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,diamagnetic and with $sp^3$ hybridization 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 of the above statements,choose the correct answer from the options given below:

$A$ tetrahedral complex ion is formed due to $........$ hybridization.

What is the geometry of the $[Ni(CO)_4]$ complex?

The type of hybridization involved in the metal ion of the $[Ni(H_2O)_6]^{2+}$ complex is:

Among the following,the species that is both tetrahedral and diamagnetic is:
