Quizplus · Accepted Answer

The compound in choice B is not consistent with the terminology of a complex because it does not contain any transition metals or other central atoms that can be bound to ligands. Instead, it is simply a salt consisting of barium ions and sulfate ions with water molecules as counterions. The other choices all contain transition metals or other central atoms that are bound to ligands, which is a characteristic feature of complexes.
