What should the team do?

Agile values active stakeholder collaboration and transparency. The best way to address stakeholder concerns is to engage them directly in the feedback loop. The PMI Agile Practice Guide (Section 7.2: Stakeholder Engagement) and Mike Griffiths’ PMI-ACP Exam Prep Book (Chapter 4: Stakeholder Engagement) both recommend inviting stakeholders to iteration reviews or demos to provide updates and gather feedback.

Option C is correct: inviting the regional sales manager to the review fosters transparency and collaboration.

Option A and B dismiss valid stakeholder input, which goes against agile principles.

Option D is overly cautious and does not proactively resolve the issue.
