Architecture Governance in TOGAF is the practice of directing and controlling architecture work so that it remains aligned with enterprise standards, principles, policies, and regulatory obligations. One of its major purposes is to ensure that architecture development and implementation comply with approved standards and required controls. This includes architecture compliance reviews, governance checkpoints, dispensations, and monitoring conformance to agreed architecture contracts and principles.
Option D is therefore the best answer because it directly describes a governance responsibility: ensuring compliance with standards and regulatory obligations. This is central to Architecture Governance.
Option A is related to stakeholder management, which is important in architecture development, but it is not the core governance practice being asked for. Option B is incorrect because the Statement of Architecture Work is a project-related deliverable, not something maintained as the main function of Architecture Governance throughout the ADM. Option C may occur in executive engagement but does not define governance practice.
Therefore, the correct answer is D .
