The Correct Option is B

Solution and Explanation

The shape of $SF_4$ is see-saw as it contains four bond pairs and one lone pair.
$XeF _{2}$ has $s p^{3} d$ hybridisation and linear geometry (due to the presence of 3 lone pairs) which is represented as

Concepts Used:

Coordination Compounds

A coordination compound holds a central metal atom or ion surrounded by various oppositely charged ions or neutral molecules. These molecules or ions are re-bonded to the metal atom or ion by a coordinate bond.

Coordination entity:

A coordination entity composes of a central metal atom or ion bonded to a fixed number of ions or molecules.

Ligands:

A molecule, ion, or group which is bonded to the metal atom or ion in a complex or coordination compound by a coordinate bond is commonly called a ligand. It may be either neutral, positively, or negatively charged.
