正解:B
During PI Planning, the Scrum Master/Team Coach (SM/TC) plays an important facilitative and support role. One key responsibility is to participate in the management review and problem-solving meeting that occurs midway through PI Planning.
This meeting allows leaders and Scrum Masters to review the teams' progress, resolve cross-team risks, address scope challenges, and ensure alignment before finalizing PI objectives. The Scrum Master's insights into team capacity, dependencies, and risks are crucial for ART-level decision-making.
From SAFe guidance:
"Scrum Masters participate in the management review and problem-solving session during PI Planning to help resolve issues that may prevent teams from meeting their objectives." Therefore, the correct answer is B. Participate in management review and problem-solving.
