Which is a supporting role a Disciplined Agile (DA) team?

In Disciplined Agile (DA), the "Specialist" is considered a supporting role. Specialists possess expertise in specific areas (e.g., security, database management) and are brought in as needed to support the primary delivery team. The supporting roles are not part of the core team but contribute specialized skills and knowledge when required.

Options A (Stakeholder), B (Team Lead), and D (Architecture Owner) are not supporting roles. Stakeholders represent end-users or business interests, while Team Leads and Architecture Owners are considered primary roles within a DA team.
