Who should the Scrum Master invite to the meeting?

Sprint planning or any task-level technical meeting should involve the development team and the product owner, as they are the key players in delivering and clarifying work. According to the PMI Agile Practice Guide (Section 3.3: Agile Roles and Responsibilities) and Mike Griffiths’ PMI-ACP Exam Prep Book (Chapter 3: Team Performance), the Scrum Master facilitates the meeting, while the development team and product owner collaborate on the details.

Option D is correct: the core team (developers) and product owner are the correct participants for story elaboration and commitment.

Option A and C involve the customer and sponsor unnecessarily for a technical planning meeting.

Option B includes " key stakeholders, " which may be overkill unless specific business input is needed.
