Using Azure Boards with Azure Repos, you have a bug work item with ID 123. You want a commit to automatically set the work item state to Resolved. What should you include in the commit message?

The correct answer is "Fixes 123". Azure DevOps (and other Git-based systems like GitHub) supports keywords in commit messages to automatically link and update work items. The keyword "Fixes" followed by the work item ID (e.g., 123) will automatically transition the linked work item to a "Resolved" or "Closed" state upon the commit being pushed and processed. "Completes 123" and "Verifies 123" are not standard keywords recognized by Azure DevOps for automatic state transitions. While they might be used for internal team communication, they won't trigger the desired automation. "Resolves AB-123" uses a non-standard prefix ("AB-") for the work item ID, which Azure DevOps would not recognize as a direct link to work item 123. The standard format is simply "ID".
