Which of the following does TOGAF describe as "a formal description of a system, or a detailed plan of the system at component level to guide its implementation"?

In the TOGAF framework, "Architecture" is fundamentally defined as a structured description of a system, which can be either a high-level overview or a detailed plan of components guiding implementation. This broad definition underpins the entire framework's approach to enterprise architecture.

An artifact is a more specific work product, such as a catalog, matrix, or diagram, created during an architecture project, rather than the overarching description of the system itself.

A deliverable is a work product that is contractually specified and then formally reviewed, agreed, and signed off by the stakeholders, which is a broader project management term.

A model is a representation of a system, often used within an architecture, but it is not the definition of architecture itself.

A view is a representation of a whole system from the perspective of a related set of concerns, which is a facet of an architecture but not the architecture itself.
