GitHub and Azure Boards are integrated. When creating a pull request in GitHub you want to automatically link the pull request to an existing Azure Boards work item by including the text AB#. To which two pull request elements can you add that text so the link is created? (Select two.)

When integrating GitHub with Azure Boards, you can automatically link a pull request to an Azure Boards work item by including the work item ID (e.g., AB123) in specific pull request elements. The title and description fields of a pull request are the designated locations where this syntax is recognized and processed by the integration. Including "AB" followed by the work item ID in either of these fields will create the link. Adding the text to a milestone or label will not create the automatic link because these fields are not parsed by the integration for work item references. A comment on the pull request is also not parsed for automatic linking; the link must be established in the initial creation or update of the title or description.
