Which statement best describes iteration and the ADM?

The TOGAF Architecture Development Method (ADM) is fundamentally an iterative process. This iteration is not confined to a single mode but occurs at multiple levels. Architects can iterate within a single phase to refine detail, cycle between phases (e.g., returning to Phase B from Phase C), and iterate over the entire ADM cycle for different scopes or to evolve the architecture over time. This flexibility allows the ADM to be adapted to the specific needs of the enterprise, making it a practical and realistic framework rather than a rigid, sequential waterfall model.

A. This is too restrictive; iteration is a continuous feature of the ADM, not just limited to the first cycle.
B. The level of detail is a key variable that is determined for each iteration based on its specific goals.
C. This is incorrect; the ADM is explicitly described as a cycle and is not meant to be followed sequentially.
