Which of the following ions is not tetrahedral?

$A$ complex involving $dsp^2$ hybridization has:

In $[NiCl_4]^{2-}$,the number of unpaired electrons is

Match the hybridisation in Column $I$ with the complexes in Column $II$. The options represent the matches for $(A), (B), (C), (D)$ respectively.

Column $I$	Column $II$
$(A)$ $sp^3$	$(i)$ $[Co(NH_3)_6]^{3+}$
$(B)$ $dsp^2$	$(ii)$ $[Ni(CO)_4]$
$(C)$ $sp^3d^2$	$(iii)$ $[Pt(NH_3)_2Cl_2]$
$(D)$ $d^2sp^3$	$(iv)$ $[CoF_6]^{3-}$
	$(v)$ $[Fe(CO)_5]$

Among $[Co(CN)_4]^{4-}, [Co(CO)_3(NO)], XeF_4, [PCl_4]^{+}, [PdCl_4]^{2-}, [ICl_4]^{-}, [Cu(CN)_4]^{3-}$ and $P_4$,the total number of species with tetrahedral geometry is:

Which of the following has the maximum number of unpaired electrons?
