In the context of roles in Disciplined Agile (DA), it is true that a person may take on more than one role within a team. DA promotes flexibility and adaptability in team roles, allowing team members to wear multiple hats depending on their skills and the team's needs. Option A (highly specialized team members) contradicts DA's principle of cross-functional teams. Option C incorrectly assigns the facilitator role to the Product Owner, and Option D does not accurately describe the Team Lead's responsibilities in DA.
