Questions: What is the best description of the relationship between employee and vehicle in the following UML class diagram? Multiple Choice Zero-to-one Zero-to-zero One-to-one One-to-many

Solution Steps

The UML class diagram shows a relationship between Employee and Vehicle with multiplicities of 0..1 on both ends. This means that an Employee can have zero or one Vehicle, and a Vehicle can be associated with zero or one Employee.

The multiplicity 0..1 on both sides indicates that the relationship is optional for both entities. Neither the Employee nor the Vehicle is required to have a counterpart in the relationship.

Given the multiplicities 0..1 on both sides, the best description of the relationship is "Zero-to-one," as it accurately reflects that each Employee can have zero or one Vehicle and vice versa.
