One Way of Describing the Bonding in XeF₂ Which Avoids

One way of describing the bonding in XeF₂ which avoids hypervalency for xenon is using the 3 centre 4 electron bond. Which combination of orbitals generate a non-bonding combination for the XeF₂ molecule?

A) In phase combination of the two F p_z orbitals and the p_z orbital on the Xe.
B) Out of phase combination of the two F p_z orbitals and the p_z orbital on the Xe.
C) In phase combination of the two F p_z orbitals and the p_x orbital on the Xe.
D) In phase combination of the two F p_x orbitals and the p_z orbital on the Xe.
