Which one of the following ions is not tetrahedral in shape?

$[Ni(PPh_3)_2Cl_2]$ is a paramagnetic complex. Identify the $INCORRECT$ statements about this complex.
$A$. The complex exhibits geometrical isomerism.
$B$. The complex is white in colour.
$C$. The calculated spin-only magnetic moment of the complex is $2.84 \ BM$.
$D$. The calculated $CFSE$ (Crystal Field Stabilization Energy) of $Ni$ in this complex is $-0.8 \Delta_0$.
$E$. The geometrical arrangement of ligands in this complex is similar to that in $Ni(CO)_4$.
Choose the correct answer from the options given below:

Match the following:

Column-$I$ Complex	Column-$II$ Structure / Geometry / Property
$A$. $[Ni(CN)_4]^{2-}$	$I$. Tetrahedral / Paramagnetic
$B$. $[Ni(CO)_4]$	$II$. Tetrahedral / Diamagnetic
$C$. $[NiCl_4]^{2-}$	$III$. Square planar / Diamagnetic

The correct match is:

The $d$-electronic configuration of $[CoCl_4]^{2-}$ in a tetrahedral crystal field is $e^m t_2^n$. The sum of '$m$' and the number of unpaired electrons is $.............$.

Dimethyl glyoxime forms a square planar complex with $Ni^{2+}$. This complex should be

Which of the following complex ions does not contain any $d$-electrons in the central metal atom?
