Explanation
The work breakdown structure (WBS) is a tool used to define the scope of work and to develop estimates. This tool creates a hierarchy of work by decomposing the project scope into smaller and smaller pieces. WBS can perform the following tasks:

It can break deliverables into work packages.
It may break activities into smaller tasks.
Answer C is incorrect. The project management plan could be helpful, in some instances, but for this
question, the best answer is WBS.
