The correct answer is B - Discuss the situation with the functional manager. The Scrum Master serves as a facilitator and servant leader, helping resolve impediments that interfere with the team's ability to deliver.
When conflicting assignments arise, the Scrum Master should facilitate communication with functional managers to clarify priorities and reinforce team commitments.
From the PMI Agile Practice Guide:
"The Scrum Master removes impediments and facilitates collaboration with stakeholders, including functional managers, to ensure the team can focus on sprint goals." (PMI Agile Practice Guide, Section 4.2 - Agile Leadership and Stakeholder Collaboration) Mike Griffiths writes:
"When external interference affects team performance, the Scrum Master should engage in dialogue with stakeholders to clarify roles and commitments, promoting alignment and removing blockers." (Mike Griffiths, PMI-ACP Exam Prep, Chapter 4 - Team Performance) Incorrect options:
* A is extreme and not within the Scrum Master's authority.
* C is unnecessarily escalatory.
* D is confrontational and undermines collaboration.
