Which of the following molecule(s) is/are having $s{p}^3{d}^2$ hybridisation for their central atom?

With 7 valence electrons, the chlorine atom in ${\mathrm{TeCl}}_6$ uses 5 of them to form a bond with the fluorine atom, while the remaining 2 electrons form a lone pair.
No. of bond pairs + No. of lone pairs $= 5+1=6=$$s{p}^3{d}^2$ for hybridization.
