Which of the following documents describes the details for each component in the WBS?

The Work Breakdown Structure (WBS) dictionary is a document that provides detailed information about each component in the WBS. While the WBS itself illustrates the hierarchy of deliverables and work, the WBS dictionary elaborates on each element. This detail typically includes a description of work, acceptance criteria, schedule milestones, cost estimates, quality requirements, and the assigned organization or individual. Its purpose is to prevent scope creep and ensure all stakeholders have a clear, common understanding of the work required for each work package.

A. WBS detail: This is a generic phrase, not the formally recognized PMI term for the document that provides detailed descriptions of WBS components.
B. Risk register: This document is used to log and track identified risks, their potential impact, and the corresponding response plans, not to describe WBS elements.
D. Project charter: This is a high-level document that formally authorizes the existence of a project and provides the project manager with authority; it does not contain detailed work package descriptions.
