The correct answer is D. Briefly introduce and explain each visual
Explanation:
A visual is any visual material such as photographs, charts or diagrams widely used during presentations to support the ideas and explanations of the speaker. Considering visuals are a tool that facilitates the task of presenting, these should be integrated into the presentation appropriately, otherwise visual can become an obstacle instead of support for the speaker.
In order to guaranteeing a visual tool is appropriate and its use is effective it is necessary to select the visual tool carefully and then know how to integrate it appropriately during the presentation, for doing this the best is to introduce the visual tool in the appropriate moment in a way it helps the audience understand better the speaker works and explain briefly to the audience why that visual is there and in what the visual shows or a short explanation of the visual itself, in this way the audience can understand the visual and how it is connected to the presentation.
Thus, the best way to explain the purpose or use of a visual to the audience is to introduce and explain it, this helps the speaker to guide the audience understanding of the visual instead of only letting them try to interpret it by themselves.
