According to the PMBOK® Guide (Project Management Body of Knowledge), specifically within the Project Resource Management knowledge area and the Plan Resource Management process, different tools are used to document team roles and relationships:

Project Organization Chart (Option B): This is a graphic display of project team members and their reporting relationships. It can be formal or informal, highly detailed or broadly framed, depending on the needs of the project. Its primary purpose is to show the hierarchy and how information flows between team members and the project manager.

Resource Calendar (Option A): This is a document that identifies the working days and shifts on which each specific resource is available. it tracks " when " a resource can work, not " who " they report to.

Resource Breakdown Structure (RBS) (Option C): This is a hierarchical list of resources related by category and resource type. It is used for planning and controlling project work (e.g., listing all " Engineers " or " Laptops " needed), but it does not typically show the reporting or command structure of the personnel.

Responsibility Assignment Matrix (RAM) (Option D): A RAM (such as a RACI chart) shows the project resources assigned to each work package. It illustrates the connections between work packages or activities and project team members, ensuring that there is only one person accountable for any single task, but it is a matrix, not an organizational hierarchy chart.

In the PMI framework, the Project Organization Chart is a subset of the Resource Management Plan and is vital for reducing confusion regarding authority and communication channels within the project team.
