The correct option is
A Linear
In XeF2XeF2, there are 55 pairs of electrons around XeXe and thus its geometry is trigonal bipyramidal.
The flourine atoms occupy linear positions while the three lone pairs occupy equatorial positions.
Thus, XeF2XeF2 is a linear molecule.
Hence the shape of XeF2XeF2 molecule is linear.
Therefore, option is A.
