When creating a Summary Zoom slide, which menu option allows you to select existing slides?

When creating a Summary Zoom slide in PowerPoint, the correct menu option to select existing slides is "Place in This Document." This option enables users to easily navigate through all the available slides within their presentation and choose which ones to include in the Summary Zoom slide. By selecting this option, users can effectively organize their presentation by summarizing key points from multiple sections into a single overview slide, thereby enhancing the audience's understanding and engagement.

The other options do not serve the same function in this context. Selecting existing slides is a direct action associated with the "Place in This Document" feature, while the other options may relate to linking or navigating differently within a presentation, but do not facilitate the selection of slides for inclusion in a Summary Zoom layout. Thus, "Place in This Document" is crucial for creating an effective summary structure by utilizing existing content from the presentation.
