Which of the following is an example of a visual aid in communication?

A PowerPoint presentation is considered a visual aid in communication because it combines text, images, charts, and other visual elements to help convey information effectively. Visual aids enhance understanding and retention by supporting the spoken word with graphical representations, allowing the audience to see concepts or data visually as they are being discussed. This multimedia aspect engages viewers and can clarify complex ideas that might be difficult to convey through verbal communication alone.

In contrast, a video presentation, while it may contain visual elements, primarily serves as a standalone medium rather than a supportive aid in a live conversation. A verbal summary is purely auditory with no visuals, thus lacking the characteristics of a visual aid. Similarly, a written report, while informative, does not provide the dynamic visual engagement associated with presentations designed to assist real-time communication.
