Which of the following is a re-usable artifact that is used to create architecture models addressing stakeholder concerns?

A Catalog is a list of architectural building blocks, not a re-usable artifact for creating models addressing concerns.

A Matrix shows relationships between architectural building blocks, not a re-usable artifact for creating models addressing concerns.

A Diagram is a visual representation of a View, but the Viewpoint is the reusable definition for creating such representations.

A View is the specific architecture model created for stakeholders, generated using a Viewpoint, not the reusable definition itself.

A Viewpoint defines the perspective and conventions from which an architecture is described, specifying how to construct a View (e.g., UML notation, specific diagram types) to address a particular set of stakeholder concerns. Viewpoints are reusable and provide a structured way to create relevant architectural representations.
