A project manager noted there were many possible features that could be incorporated into a project, and the customers wavered about whether to include particular features. Which of the following is the BEST approach to ensure appropriate delivery of the project?

A. In one section of the project charter, specify which features are included in the project, in another section, specify which features are not included in the project.
B. The scope statement should enumerate which features are included in the project and which features are not included in the project.
C. At the beginning and end of every meeting, the project manager should consistently remind the project team which features are included in the project and which features are not included in the project.
D. The project requirements document lists all the features that are included in the project, and the project manager diligently ensures that features not included in the project are not included in the MOU with the customer.
