How is the default tab in a workspace determined?

The correct answer is A. It is the tab that has been set as the default tab. Relativity’s Tabs documentation states that a tab has a Set as Default Tab toggle, and when this is turned on, that tab serves as the workspace’s default tab. Reviewers logging into the workspace are taken to that default tab. Relativity also notes that if a reviewer does not have access to that default tab, the user is directed to the Documents tab instead.

This means the default tab is not determined merely by tab order. The lowest order number affects where a tab appears in the sidebar, but not which tab is designated as the workspace default. The Admin tab and Documents tab are not always the default either; Documents only acts as the fallback if the user lacks access to the selected default tab. Therefore, the correct answer is that the default tab is the one explicitly set as the default tab .
