Solution

$\begin{aligned}<br />& \mathrm{PF}_5: 5 \sigma+0 \ell \mathrm{p} \rightarrow \mathrm{sp}^3 \mathrm{~d} \\<br>& \mathrm{SF}_6: 6 \sigma+0 \ell \mathrm{p} \rightarrow \mathrm{sp}^3 \mathrm{~d}^2 \\<br>& \mathrm{Ni}(\mathrm{CO})_4: \mathrm{Ni} \rightarrow 0<br />\end{aligned}$
In presence of ligand field :-

$\left[\mathrm{PtCl}_4\right]^{2-}: \mathrm{Pt} \rightarrow+2$
In presence of ligand field :-

Hence, the correct answer is option: 'A'.
