Explanation
The definition of done (DoD) is a clear and concise list of requirements that a project increment must meet before it is considered complete and potentially releasable1. The project manager should check on the DoD for the project to ensure that the product meets the quality standards and stakeholder expectations before deploying it. Ignoring the stakeholder's request (A) or expediting the final deployment (D) may compromise the quality and value of the product. Updating the acceptance criteria (B) may introduce scope changes and delays in the project. References: 1: PMBOK Guide, 6th Edition, p. 176.
