Which statement is true about the diagram?

Consider the following diagram:

Which statement is true about the diagram?
A . Within G you may refer to v:K by gh.H::v. .
B . From within H it is impossible to reach the v within G.
C . The package Pckg cannot have two definitions of v as shown in the diagram.
D . v will indicate different elements depending on where you refer to v within Pckg

Answer: D

Explanation:

The diagram you provided shows two classes, G and H, which are within a package named Pckg. Each class has an attribute named ‘v’ with different visibility and type indicators. The attribute ‘v’ in class G has visibility ‘private’ (denoted by ‘-‘), and in class H, it is ‘protected’ (denoted by ‘#’). This suggests that the scope of each ‘v’ is limited to its respective class. Therefore, when you refer to ‘v’ within the package, its meaning depends on the context or the namespace from which it’s accessed.

Reference: UML 2.x Superstructure Specification: This defines the rules for scopes and namespaces in UML. It clarifies how elements with the same name can coexist in different namespaces and how their references would differ based on the context.

UML 2.x Infrastructure Specification: Provides the foundational concepts for UML, including the semantics of structured classifiers and namespaces which pertain to the interpretation of the ‘v’ attribute in different classes.
