Using the "Design" tab in PowerPoint primarily allows users to select a theme for their presentation. Themes are essential because they provide a cohesive visual style, which includes color schemes, font choices, and overall layout. This contributes significantly to the professional appearance of a presentation, ensuring that it is visually appealing and that content is presented in an organized manner. By selecting a suitable theme from the Design tab, users can enhance the aesthetic quality of their slides and maintain consistency throughout the presentation.

While the other options involve important features in PowerPoint, they are not functionalities associated with the Design tab. Sound effects are usually managed through the "Insert" or "Transitions" tabs, tables are inserted through the "Insert" tab, and animations for text are found under the "Animations" tab. Each of these functionalities is essential in creating an effective presentation but do not pertain directly to the purpose of the Design tab.
