What should the Scrum Master do next?

According to thePMI Agile Practice Guide (Section 7.2.1), the Scrum Master’s role includesremoving impediments and shielding the team from outside interference. A team member being pulled into work on a different project is a classic example of an impediment. Recording the issue in a risk register is appropriate, but more importantly,the Scrum Master must communicate and resolve the issue.

Mike Griffiths in hisPMI-ACP Exam Prep Book (Chapter 3: Team Performance)emphasizes that agile teams require full dedication and protection from context switching, as multitasking reduces productivity and increases error rates. Merely documenting the issue is not enough—the Scrum Master must take steps toescalate and resolve the interference, potentially by negotiating with the former supervisor or re-clarifying role boundaries.

Therefore,Option Cis correct as it involvesactively addressing the threatrather than passively monitoring or adjusting around it.
