What action do you take to change the theme variant in PowerPoint?

To change the theme variant in PowerPoint, selecting the Design tab and choosing the appropriate variant is the correct approach. The Design tab is specifically designed to handle visual aspects of your presentation, such as themes, colors, and variants.

Within this tab, you can find the option to see different theme variants associated with the chosen theme. By clicking on the relevant variant, you effectively apply that specific style to your slides, allowing for a cohesive and visually appealing presentation. This process focuses on enhancing the overall aesthetics while maintaining a professional look.

The other choices do not accurately lead to changing the theme variant as efficiently or correctly. For example, the Edit Theme options provide more in-depth customization rather than switching variants. Slide Sorter view is meant for organizing slides rather than altering design aspects. Lastly, accessing the View tab does not give you direct control over theme variants, which are specifically managed through the Design tab. Thus, engaging with the Design tab for this task is essential for effective presentation design.
