During PI Planning, the Coach Sync is a coordination meeting among Scrum Masters, Team Coaches, and the Release Train Engineer (RTE). One of its key purposes is to ensure alignment and visibility across all Agile Teams on the Agile Release Train (ART).

A Scrum Master/Team Coach must be prepared to answer the question: ''Have you identified any ART risks?'' Identifying, communicating, and escalating risks early supports proactive management and helps the ART achieve its PI objectives. These risks are later reviewed and categorized during the ROAM (Resolved, Owned, Accepted, Mitigated) process in PI Planning.

From SAFe guidance:

''During the Scrum Master/Team Coach Sync at PI Planning, teams share progress, dependencies, and risks that may impact the ART, ensuring transparency and alignment.''

Therefore, the correct answer is C. Have you identified any ART risks?, as risk visibility and management are central to successful PI execution.
