Angular or bent molecular geometry occurs when a central atom is bonded to two or more other atoms and has one or two lone pairs of electrons. This geometry results in a bent or V-shaped molecule. Among the given options, the fluoride that exhibits angular geometry is SnF2 (option C).

Explanation:

SnF2 (Tin(II) fluoride):
- Tin (Sn) is the central atom in SnF2.
- Fluorine (F) atoms are bonded to the central tin atom.
- SnF2 molecule has a bent or angular shape.
- The tin atom has two lone pairs of electrons and forms two bonds with the fluorine atoms.
- The presence of two lone pairs of electrons on the tin atom leads to the bent or angular geometry.

BeF2 (Beryllium fluoride):
- Beryllium (Be) is the central atom in BeF2.
- Fluorine (F) atoms are bonded to the central beryllium atom.
- BeF2 molecule has a linear shape.
- The beryllium atom has no lone pairs of electrons and forms two bonds with the fluorine atoms.
- The absence of lone pairs of electrons on the beryllium atom results in a linear geometry.

ZnF2 (Zinc fluoride):
- Zinc (Zn) is the central atom in ZnF2.
- Fluorine (F) atoms are bonded to the central zinc atom.
- ZnF2 molecule has a linear shape.
- The zinc atom has no lone pairs of electrons and forms two bonds with the fluorine atoms.
- The absence of lone pairs of electrons on the zinc atom results in a linear geometry.

XeF2 (Xenon difluoride):
- Xenon (Xe) is the central atom in XeF2.
- Fluorine (F) atoms are bonded to the central xenon atom.
- XeF2 molecule has a linear shape.
- The xenon atom has no lone pairs of electrons and forms two bonds with the fluorine atoms.
- The absence of lone pairs of electrons on the xenon atom results in a linear geometry.

Therefore, among the given options, only SnF2 exhibits angular or bent molecular geometry.
