A project manager is leading a project for a pharmaceutical company.

The correct answer is B because the scenario requires disciplined integrated project management rather than an immediate, informal, or purely administrative reaction. The selected response — B. Initiate the project closing process. — directly addresses the condition described in the question and keeps the project aligned with authorized objectives. PMBOK-aligned practice requires the project manager to analyze the situation, use the right plan or governance mechanism, and align decisions with project value and constraints. This is especially important when project constraints, stakeholder expectations, quality expectations, delivery cadence, or business value may be affected. The competing options are weaker because they either bypass the accountable role, defer action without analysis, escalate before the project manager has prepared decision-quality information, or solve a symptom without correcting the underlying process issue. The selected answer also preserves transparency, ownership, and traceability, which are essential for sound project governance and effective delivery.
