# In Agile (particularly Scrum), the Product Owner is solely responsible for backlog prioritization. The Scrum Master facilitates the process but does not have authority over content decisions. When a conflict arises about prioritization, the resolution lies in re-establishing role clarity-not in the project manager stepping in to override roles. The correct action is to reinforce Agile roles and responsibilities, particularly that the Product Owner owns prioritization. This aligns with the Agile Practice Guide and the Scrum Guide. Option B may be helpful but delays resolution and misses the fundamental answer. Option C incorrectly shifts authority to the Scrum Master. Option D bypasses the Agile team structure and disrespects team autonomy. References: Agile Practice Guide, Ch. 3: Roles and Responsibilities in Agile Teams Scrum Guide: Product Owner Responsibilities
