What tool can be used to visually represent project deliverables?

Choosing the Work Breakdown Structure (WBS) as the correct answer highlights its primary function of visually representing project deliverables. The WBS breaks down the entire project into smaller, more manageable components, showcasing each product, service, or result that the project will deliver. By organizing deliverables hierarchically, the WBS provides a clear visual representation of how different tasks and activities contribute to the overall goals of the project.

The structure allows project managers and team members to see the scope of the project at a glance, making it easier to understand how each element fits into the larger picture. This clarity is crucial for effective planning, communication, and monitoring of project progress, as it delineates responsibilities and expectations.

In contrast, other options serve different purposes. A Gantt chart is primarily a scheduling tool that visually represents project timelines and task durations, rather than the deliverables themselves. A risk register lists potential risks and does not focus on deliverables, while a project schedule organizes tasks by time but does not inherently display the hierarchy or structure of deliverables as the WBS does. Thus, the unique capability of the WBS to showcase project deliverables in a clear, organized manner makes it the most appropriate choice.
