Which of the following roles would fall under that of a "specialist' on a Disciplined Agile Delivery Team?

Disciplined Agile Delivery (DAD) defines Business Analyst as a form of “Domain Expert,” which is one of the secondary, specialist roles that join the team only when their focused expertise is required. Project Manager is not a DAD role, and both Stakeholder and Product Owner are primary—not specialist—roles.

A. Project Manager – Traditional role; DAD work is guided by Team Lead and Product Owner, so it is neither primary nor specialist.
B. Stakeholder – External primary role providing requirements/feedback, not a specialist inside the delivery team.
C. Product Owner – Primary role owning vision and backlog, not a secondary specialist.
