The UML notation 0..1 corresponds to an optional relationship, where an object of the class on the side with 0..1 can either have no association or can be associated with one object of the class on the other side. In this case, an employee can have no spouse or one spouse, making option B the correct answer. Options A, C, and D correspond to different notations, such as 0..* for many direct reports or 1..1 for one office manager.
