Upon joining a team, a Scrum Master should focus on facilitating team collaboration, removing impediments, and creating a psychologically safe space. The PMI Agile Practice Guide (Section 3.3: Scrum Master Role) and Mike Griffiths (Chapter 3: Team Performance) stress that early efforts should center on servant leadership, helping the team identify and solve their own challenges.

Option C is correct: supporting the team through facilitation reflects the core role of a Scrum Master.

Option A is prescriptive and not aligned with cross-functional team philosophy.

Option B may be necessary later, but first, trust and team dynamics must be established.

Option D falls under the Product Owner’s responsibility, not the Scrum Master’s.
