"QueryCustomerFromParcel" is annotated with the «transformation» stereotype, which indicates that it is a behavior element that specifies how to convert input objects into output objects. Therefore, the answer is D, a Behavior element, for example, an Activity, State Machine, or OpaqueBehavior. In UML, the «transformation» stereotype is applied to specify that an action or activity is responsible for transforming an input (in this case, "Parcel") into an output ("Customer"), typically by employing a specific behavior element.

References:

• UML 2.5 Specification: Section on Object Flows describes how transformations can be used within activity diagrams to turn inputs into outputs using behavior elements.

The capability that enables the discovery and manipulation of metaobjects and metadata is Reflection. In the context of the Meta-Object Facility (MOF), reflection allows you to examine and interact with the structure and semantics of metamodels, models, and their elements. It provides a way to introspect and dynamically access information about the modeling constructs, such as classes, attributes, relationships, and constraints.

In the MOF class hierarchy, the class ‘Element’ sits at the top. It is the superclass of all classes defined in MOF and is an implicit superclass of all metaclasses defined using MOF1. This superclass relationship to ‘Element’ does not need to be explicitly declared in the metamodels.
