The best answer is B. Illustrate the decision pathway using LIME for localized interpretability . In PMI- CPMAI, one of the core responsibilities under Support Responsible and Trustworthy AI Efforts is to establish explainability requirements for stakeholder communication and to implement model interpretability tools and techniques . That makes this option the strongest match because the board is explicitly described as nontechnical and needs a comprehensible explanation of how the model reached a decision. LIME is an interpretability technique designed to explain individual predictions in a human- understandable way, which fits the scenario far better than performance charts or threshold metrics.
The other options are more focused on evaluation metrics than explainability for business stakeholders .
Confusion matrices, precision-recall trade-offs, and ROC curves are useful for model assessment, but they are typically more technical and less effective for explaining a specific decision pathway to executives. PMI materials emphasize transparency, scrutiny, and understanding of AI outputs, especially when stakeholder trust and alignment with business objectives are important. That is why an interpretability method such as LIME is the most PMI-aligned choice here.
