What is a hyperlink in PowerPoint?

A hyperlink in PowerPoint serves as a connection that can guide users to either an external resource—such as a webpage, document, or multimedia file—or another slide within the same presentation. This functionality allows for enhanced interactivity, enabling presenters to create engaging experiences by linking to related content or resources. By using hyperlinks, presenters can direct their audience seamlessly from one point to another, facilitating navigation and providing additional context where necessary.

The ability to link to resources outside the presentation or to specific slides aids in organizing information and enhancing the overall flow of the presentation. This contrasts with the other options, which describe different features that do not involve the core functionality of hyperlinks. For example, transitioning between slides is more related to slide animations and transitions, while embedding videos pertains to media integration. Exporting slides as a PDF is an output function that does not involve the dynamic linking capabilities that hyperlinks provide. Thus, the defining characteristic of a hyperlink is its role as a navigational tool, making the selected answer the most accurate description of its function in PowerPoint.
