* The image shows a diagram that illustrates the basic concepts of architecture description as defined by the ISO/IEC/IEEE 42010:2011 standard1, which is also adopted by the TOGAF standard2.
* According to the ISO/IEC/IEEE 42010:2011 standard, an architecture description is a work product used to express an architecture, and it consists of one or more architecture views1.
* An architecture view is a representation of a system from the perspective of a related set of concerns, and it conforms to an architecture viewpoint1.
* An architecture viewpoint is a specification of the conventions for constructing and using an architecture view to address specific stakeholder concerns1.
* Therefore, the correct answer is option A, which identifies the items labeled as "A" and "B" in the image as an architecture viewpoint and an architecture view, respectively. Reference:
