Which artifact collects all the work flowing to the team?

TheProduct Backlogis the artifact that collects all the work flowing to the team in Agile practices, including Disciplined Agile (DA). It is an ordered list of everything that might be needed in the product, serving as the single source of work undertaken by the team. This backlog includes user stories, features, enhancements, bug fixes, and technical tasks. It is prioritized by the Product Owner to ensure that the team works on the most valuable items first.

Options B (Business backlog) is not a standard Agile artifact. Option C (Iteration backlog) is a subset of the Product Backlog, containing items chosen for the current iteration. Option D (Release roadmap) is a higher-level plan for future releases, not a collection of all work items.
