The correct option is Scrum process.

The Scrum process provides a Product Backlog Item work item type and includes support for Bugs and board-based workflows, including Kanban boards. This makes it the appropriate choice when a team needs to create and manage product backlog items and log bugs on a Kanban board in Azure Boards.

The CMMI process is oriented toward formal project and process management and uses Requirement and Change Request work items rather than Product Backlog Item, so it does not match the Scrum artifact names the question specifies.

The Basic process is a simplified template with a minimal set of work item types and it does not provide the full Product Backlog Item structure or the richer backlog management features that Scrum offers.

The Agile process uses User Story as the primary backlog item rather than Product Backlog Item, and it follows Agile terminology instead of Scrum artifacts, so it does not directly match the requirement to use Product Backlog Items.
