In which of the following molecules, sigma bonds formed by the overlap of ${sp}^3 \mathrm{d}$ and p-orbitals are absent

${\mathrm{ClO}}_4^{-}$(Perchlorate ion)
No. of electron pairs $=\frac{1}{2}[\mathrm{V}+\mathrm{M}-\mathrm{C}+\mathrm{A}]$
V= No of valency electrons
M= No of monovalent atoms bonded to the central atom
C=Total charge on the cation
A=Total charge on the anion
Hybridization $=\frac{1}{2}[7+0-0+1]$$=8/2=4\Rightarrow {\mathrm{sp}}^3$- hybridization
$\therefore \mathrm{Cl}$ in ${\mathrm{ClO}}_4^{-}$ uses ${\mathrm{sp}}^3$ hybrid orbitals.
