How does PIP (Picture-In-Picture) function in a presentation?

PIP, or Picture-In-Picture, is a feature that enhances presentations by allowing two program feeds to be viewed concurrently. This functionality is particularly beneficial in engaging audiences as it enables a primary video to be displayed prominently while a secondary video, such as a speaker or relevant graphics, appears in a smaller window overlaying the main content. This method enriches the viewing experience by providing additional context or commentary without detracting from the main presentation.

In contrast, the other options do not accurately describe the PIP feature. Displaying three screens simultaneously does not align with the typical function of PIP, which focuses on a combination of two views. Showcasing a single program feed or including only audio are also not representative of PIP's multimedia capabilities, which are primarily visual and designed to complement the main content dynamic.
