How should the agile team address this?

In agile, early and frequent feedback from stakeholders and clients is critical to ensure that what is being built delivers the intended value. The PMI Agile Practice Guide (Section 5.5 and Section 7.2.2) promotes regular product review sessions (e.g., sprint reviews) with stakeholders to validate progress and obtain immediate feedback.

Mike Griffiths (PMI-ACP Exam Prep Book, Chapter 6: Value-Driven Delivery) explains that product validation is continuous and not left to the end of the project. Regular review sessions allow clients to confirm that the product meets expectations, reducing the risk of building the wrong solution.

Therefore, Option D is correct: holding product review sessions with the client aligns with agile values of transparency, collaboration, and value delivery.
