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

'WBS detail' is not a recognized formal project management document - the correct and standard term for this artifact is the WBS dictionary.

The risk register documents identified risks, their probability and impact, and response strategies - it does not describe the content or boundaries of WBS components.

The WBS dictionary is the companion document to the WBS that provides detailed information for each WBS component, including scope descriptions, deliverables, acceptance criteria, responsible parties, and cost and schedule data. It ensures all stakeholders share a precise and consistent understanding of every work package and control account.

The project charter authorizes the project and designates the project manager but does not contain granular descriptions of individual WBS elements.
