Correct answer & explanation
✓
To provide a hierarchical representation of all work required to complete the project deliverables
The WBS is a hierarchical decomposition of the total scope of work to be carried out by the project team. It organizes and defines the total scope, with work packages at the lowest level representing deliverables that can be assigned, estimated, and managed.
