You have work items with IDs 456, 457, and 458. You must create a pull request linked to all three items and automatically set work item 456 to Done. What should you include in the commit message?

The correct option is "Fixes AB456, AB457, AB458" because Azure DevOps (formerly VSTS/TFS) uses specific syntax for linking work items and triggering state transitions from commit messages. The "Fixes" keyword, followed by the work item ID, automatically transitions the specified work item to a "Done" or "Closed" state, depending on the process template. To link multiple work items, you list them separated by commas. The "AB" prefix is a common convention or project-specific identifier often used in Azure DevOps to distinguish work item IDs, though the exact prefix can vary. The other options are incorrect because they either lack the "Fixes" keyword to trigger the state change, use incorrect syntax for linking, or omit the necessary prefix for the work item IDs.
