The Resource Breakdown Structure (RBS) is specifically designed to provide a hierarchical representation of resources categorized by both function and type within a project. It helps project managers and teams visualize all the resources needed for a project, organized in a manner that displays the relationships and dependencies among them. This structured approach not only aids in the planning process but also enhances resource allocation and management throughout the project's lifecycle.

In contrast, an organizational chart primarily focuses on the structure of an organization, illustrating roles and relationships among staff. The Responsibility Assignment Matrix (RAM) is used to assign responsibilities for tasks and deliverables, pairing individuals or teams with specific project responsibilities without detailing resources' functional hierarchies. A RACI chart is a type of RAM that identifies who is Responsible, Accountable, Consulted, and Informed for each task, but it does not provide a breakdown of the resources in the same hierarchical manner as an RBS. Thus, the Resource Breakdown Structure is the most fitting answer as it directly aligns with the definition of a hierarchical list of resources by function and type in project management.
