The correct answer is D because the Scrum Master participates in the Sprint Retrospective as a member of the Scrum Team and facilitates the event when needed. According to the Scrum Guide, the Sprint Retrospective exists so the Scrum Team can inspect how the last Sprint went regarding individuals, interactions, processes, tools, and their Definition of Done, and then identify improvements to increase quality and effectiveness. The Scrum Master helps ensure that Scrum events take place and are positive, productive, and kept within the timebox. That includes helping the team use the Retrospective effectively.

Option A is incorrect because the Scrum Master is not merely a note-taker or scribe. Option B is incorrect because the Sprint Retrospective is for the Scrum Team, not a management reporting session. Option C is incorrect because action items are not ''prioritized'' by the Scrum Master alone; improvements are identified collaboratively by the Scrum Team.

The Scrum Master's role is to support meaningful reflection, encourage openness, and help the team turn insights into practical improvements within the Scrum framework.
