2. "A variety of media used to communicate an idea" - This option does not describe a caption. It refers to the concept of using different forms of media to convey an idea, which is not specifically related to captions.

3. "A visual representation" - This option does not exclusively describe a caption. While captions can be associated with visual representations, they are not solely limited to visual elements.
