If Marielena plays a movie clip during a speech about special effects, which type of presentational aid is being used?

In this scenario, Marielena is using an audiovisual presentational aid. Audiovisual aids incorporate both visual components, such as video clips, and auditory elements, such as sound. By playing a movie clip, she effectively engages her audience with a dynamic medium that supports her speech about special effects.

This type of aid is particularly beneficial when discussing topics that involve movement or sound, as it allows the audience to experience the subject matter in a more immersive way. The visual aspect of the movie clip helps to illustrate her points clearly and keeps the audience's attention.
