The class that creates a justified tab navigation in Bootstrap is indeed the one that includes "nav-justified." When this class is applied to a navigation component, it causes the tab links to stretch and evenly distribute within the available horizontal space, ensuring they align in a visually appealing and organized manner. This approach not only enhances the aesthetic of the tab navigation but also improves usability, as users can more easily identify and click on the options available.

In contrast, the other choices do not offer justified tab navigation. The "nav-stacked" class is used for vertical navigation, and simply using "nav-tabs" will create standard tab links without any justification. The last choice, with "justified," is not a valid class in Bootstrap, which makes it ineffective for achieving the desired tab styling. Therefore, the correct use of "nav-justified" is essential for creating a clean and professional tab navigation layout.
