What must you click on to modify the base branch in the user story?

To modify the base branch in the user story, accessing the Advanced Settings is necessary. This area provides a dedicated interface for configuring more specific aspects of the user story, including the base branch selection. Adjusting the base branch is a crucial part of managing how changes are integrated and aligned within the overall development process.

The Advanced Settings allow you to drill down into these configurations, ensuring that you can make informed choices about where your changes will be directed. This is particularly important in environments where multiple branches may be active and changes need to be carefully routed to maintain the integrity of the codebase.

In contrast, the other options serve different functions within the workflow. Applying Changes typically refers to finalizing modifications made, while Committing Changes is associated with saving those changes to the repository. Reviewing the branch usually involves looking at the current branch specifics instead of modifying them, which is why the Advanced Settings option is the appropriate choice for adjusting the base branch.
