Which option allows you to add descriptors or comments that only the presenter can see during a presentation?

The option that allows you to add descriptors or comments that only the presenter can see during a presentation is referred to as Speaker Notes. This feature is designed specifically for presenters to include additional information, reminders, or cues that can support their delivery of the content without being visible to the audience.

Speaker Notes are located in a separate area of the presentation software, ensuring that only the presenter can view these notes while the audience sees only the slides. This capability helps presenters stay organized and focused on their key points, enhancing their ability to convey information effectively.

In contrast, while Presenter Notes may seem like a potential choice, the correct terminology in many presentation platforms is "Speaker Notes," emphasizing their purpose for the individual speaking rather than general layout or formatting elements like Slide Layout or interactive elements such as a Comment Box.
