A Work Breakdown Structure (WBS) plays a crucial role in project management by providing a hierarchical decomposition of the total scope of work required for a project. This structured breakdown allows project managers and teams to clearly define and organize all the deliverables, tasks, and subtasks that need to be completed. By doing so, it facilitates better planning, resource allocation, and task management.

The hierarchical nature of the WBS makes it easier for teams to visualize the work required, understand the project scope in detail, and ensure that no part of the work is overlooked. It serves as a foundational tool for developing further project plans, enabling effective communication among stakeholders and aiding in tracking progress throughout the project's lifecycle.

The other options, while relevant to project management, do not accurately describe the primary function of a WBS. The WBS is not designed to list team members and their roles, graphically represent risks, or outline a timeline of milestones. Instead, its focus is on breaking down the entirety of the project scope into manageable components, which supports all other planning activities.
