You manage project work items in Azure Boards and code in GitHub. You have work items with IDs 456, 457, and 458. You must create a pull request that links all three work items and sets work item 456 to Done. What should you add to the commit message?

The correct answer is "Fixes AB456, A8457, A8458". When integrating Azure Boards with GitHub, specific keywords followed by a work item ID (e.g., "Fixes ID", "Closes ID", "Resolves ID") automatically link the commit or pull request to the work item and transition its state. The "Fixes" keyword is used to close a work item. To link multiple work items, you list them separated by commas. The "AB" prefix is not standard for Azure Boards work item IDs in GitHub integrations; typically, just the numeric ID is sufficient. However, the core mechanism of using a keyword like "Fixes" to transition a work item's state and linking multiple items is key. Options like "Done 456" or just listing IDs without a keyword will link the work items but will not automatically change their state to "Done." The correct format for linking and transitioning is Keyword ID.
