Chapter 9 - Molecular Geometry and Bonding Theories - Exercises - Page 388: 9.3d

There is only one possible electron domain geometry, which is octahedral.

There are five atoms bonded to the central atom, and the atoms have a bond angle of 90 degrees. This means that there must be a square pyramid molecular geometry. Thus, there must be one lone pair of electrons on the central atom. Because there are five bonded atoms and one lone pair, the shape in d) must have an octahedral electron domain geometry.
