Correct answer & explanation
✓
Work package
The work package is the lowest level of the WBS and is the basis for estimating, scheduling, and assigning resources. It represents a discrete deliverable that can be planned, budgeted, and monitored. The WBS dictionary (A) provides supporting details but is not the basis for estimating. Control accounts (B) are management control points at higher levels. Planning packages (C) are temporary placeholders for future work. Therefore, D is correct.
