The electron geometry is determined using the VSEPR theory, which predicts that XeO₃ has four electron domains, giving a tetrahedral electron geometry. The molecular geometry takes into account the positions of the atoms alone, not the lone pairs, so the molecular geometry is trigonal pyramidal because the lone pair on the sulfur pushes the bonding pairs down. Finally, the molecule is polar because of the lone pair on the sulfur atom, which creates an uneven distribution of electron density around the molecule. Choice B correctly predicts all of these properties.
