The correct answer is B - Prioritize the most valuable product features in the backlog first.
Agile prioritization focuses on delivering value early and frequently. Coaching the product owner to understand value-based prioritization ensures that the most critical features are built and validated first.
PMI Agile Practice Guide:
"Agile teams focus on delivering the highest value items first. The product owner prioritizes the backlog based on business value, risk, and stakeholder input." (PMI Agile Practice Guide, Section 3.3 - Backlog Management) Mike Griffiths:
"Product backlog prioritization is value-driven. The product owner should assess each item's value and prioritize those that deliver the greatest return or strategic impact." (PMI-ACP Exam Prep, Chapter 3 - Value-Driven Delivery) Incorrect options:
* A misinterprets story points as a priority metric-story points measure effort, not value.
* C addresses risk but not value.
* D refers to Minimum Viable Product (MVP), which is a release planning technique, not a backlog sorting method.
