A project manager notices that a product owner has been unresponsive over the last few...

This question belongs to the People domain because it focuses on communication effectiveness, stakeholder engagement, and resolving a collaboration problem before escalating it. PMI guidance emphasizes that project managers should understand stakeholder concerns and communication barriers rather than immediately jump to escalation or process changes. Since the product owner is unresponsive and incomplete information is causing rework, the best first step is to understand the underlying reason for the behavior. A root cause analysis helps determine whether the issue is workload, lack of clarity, competing priorities, insufficient product knowledge, or another blocker.

Option A is premature because escalation should usually come after trying to understand and address the issue directly. Option B treats the symptom by adding time, but it does not solve the information gap. Option D weakens collaboration and may make the communication problem worse. PMP-style reasoning favors diagnosing the cause before deciding on the corrective action. Once the cause is clear, the project manager can coach, support, reassign responsibilities, or escalate if needed.
