Work item itemA is dependent on itemB. Which action in the Azure DevOps web portal defines this dependency correctly?

The correct answer defines the dependency using the "Successor" link type, which is appropriate when itemA (the successor) depends on itemB (the predecessor). This is done from the Backlogs view, where you can easily manage work item relationships. Incorrect options: Using "Related" is a generic link type and doesn't explicitly define a dependency. "References" is typically used for linking to external resources or other work items that are referenced, not for direct dependencies. "Affected By" indicates that itemA is affected by itemB, which is the inverse of the desired dependency (itemA depends on itemB). Also, creating links from Queries is not the standard or most efficient way to establish work item dependencies.
