Complete the following sentence. In the ADM documents which are under development and have not undergone any formal review and approval process are_______________.

In the TOGAF Architecture Development Method (ADM), document management and versioning conventions dictate that documents which are currently under development and have not yet undergone any formal review and approval process are officially called "draft". This terminology ensures clear communication among stakeholders regarding the maturity and reliability of architecture artifacts. Once a draft undergoes review, it may progress to higher version numbers (e.g., Version 0.9 for final review, and Version 1.0 for formally approved documents).

B. "Invalid" is incorrect because draft documents are legitimate, valid work-in-progress artifacts necessary for the architecture development process.
C. "In between phases" is incorrect because documents are actively developed and drafted during the execution of ADM phases, not just between them.
D. "Version 0.1" refers to a specific milestone (usually a high-level outline), whereas "draft" is the overarching term for any unapproved document under development.
