Answer: C

Explanation:

In UML, profiles are applied to specific model elements to adapt the UML metamodel to different domains or platforms. The provided diagram shows a UML package diagram within which the «Versioning» profile is applied to the "Business Logic" package, and the «DBProfile» is applied to the "Data" package. This is a correct use of profiles in UML as they allow the customization of parts of a model by applying additional constraints and stereotypes to specific packages or classes. There is no restriction in UML that a profile cannot be applied to multiple packages in the model simultaneously, and profiles do not necessarily need to be members of the namespace of the model they are applied to; they can be defined externally. Therefore, the scenario presented is a correct application of two different profiles to two distinct packages within the same model, conforming to the UML 2.x Superstructure Specification.
