Analysis of Options:

XeF₂ (Option a):
- Geometry: Linear
- Atoms in the same plane: The two fluorine atoms and xenon atom lie on the same line, which is a plane.
- Count of atoms in the same plane: 3.
PCl₅ (Option b):
- Geometry: Trigonal bipyramidal
- Atoms in the same plane: In the trigonal bipyramidal structure, the three equatorial chlorine atoms lie in the same plane as phosphorus.
- Count of atoms in the same plane: 4.
AsH₄⁺ (Option c):
- Geometry: Tetrahedral
- Atoms in the same plane: In a tetrahedral geometry, no three atoms lie in the same plane.
- Count of atoms in the same plane: 2 (at most, if you consider the projection).
XeF₄ (Option d):
- Geometry: Square planar
- Atoms in the same plane: In a square planar geometry, the central xenon atom and all four fluorine atoms lie in the same plane.
- Count of atoms in the same plane: 5.

Answer: d: XeF₄

In XeF₄, the maximum number of atoms (5) lie in the same plane due to its square planar geometry.
