(P) AlCl₄⁻: The hybridization is sp³, so no d-orbitals are used (4).

(Q) SF₄: The hybridization is sp³d; for trigonal bipyramidal geometry, the $d_{z^{2}}$ orbital is used (1).

(R) IF₇: The hybridization is sp³d³, which utilizes $d_{x y}$ , $d_{yz}$ , and $d_{x z}$ or specifically $d_{x y}$ (2) among the given options.

(S) XeF₄: The hybridization is sp³d²; for square planar geometry, the $d_{z^{2}} + d_{x^{2} - y^{2}}$ orbitals are used (3).

The correct sequence is P $\to$ 4; Q $\to$ 1; R $\to$ 2; S $\to$ 3, matching Option (D).

List - I (Molecules)	List - II (d- orbital(s) in hybridisation )
(P) $AlCl_{4}^{-}$	(1) $d_{z^{2}}$ only
(Q) $SF_{4}$	(2) $d_{x y}$
(R) $IF_{7}$	(3) $d_{z^{2}} + d_{x^{2} - y^{2}}$ only
(S) $XeF_{4}$	(4) No d-orbital(s) is/are used
