The correct answer is:

Analyzing each complex based on Valence Bond Theory (VBT):

is is a strong field ligand (SFL) for , causing pairing. This leaves two orbitals vacant. Hybridization is (Inner orbital complex). Statement A is correct.

is is a weak field ligand (WFL). No pairing occurs. To accommodate 6 ligands, it uses , and orbitals. Hybridization is (Outer orbital complex). Statement B is correct.

:
is is a WFL. No pairing occurs. Hybridization is (Outer orbital complex). Statement C is incorrect because it mentions .
:
is is a WFL. No pairing occurs. Hybridization is (Outer orbital complex). Statement D is correct.
(E) :
is is a SFL , causing pairing of the two unpaired electrons in . This leaves one orbital vacant. Hybridization is (Square planar, Inner orbital complex). Statement E is incorrect because it mentions .
