A project manager is involved with minimizing unauthorized changes to the project. Which of the following will BEST assist with these changes?

A risk register identifies and tracks potential risks, but does not directly control or prevent unauthorized changes to the project's requirements.

Quality management metrics are used to measure the quality of project deliverables, which is different from preventing unauthorized modifications to the project's scope.

The scope statement provides a detailed description of the project's deliverables, boundaries, and acceptance criteria, serving as the definitive baseline. By clearly outlining what is included and excluded, it acts as the primary tool to evaluate and prevent unauthorized additions or alterations to the project.

Budget scope defines the financial limits of a project but does not specify the functional or technical boundaries necessary to prevent unauthorized changes to the project's features or work.
