This question fits the People domain because it concerns stakeholder engagement, relationship management, and resolving approval delays through direct communication. PMI's PMP Examination Content Outline emphasizes engaging stakeholders, understanding their needs, and addressing concerns before escalating issues. Since the stakeholder is new to the project and is withholding approval, the project manager should first meet with that stakeholder to understand the cause of the delay. The underlying problem may involve unclear expectations, insufficient information, misunderstanding of acceptance criteria, or concern about deliverable quality. Direct discussion is the most appropriate first step.
Option B escalates too early and assumes political influence is required before understanding the issue.
Option C is premature because workarounds should not be developed before the cause of non-approval is known. Option D may become necessary later if the issue persists, but PMP-style thinking favors resolving concerns at the lowest appropriate level first. A direct meeting helps restore alignment, clarify expectations, and potentially remove a barrier to approval without unnecessary escalation. That is why option A is the best answer.
