Media sources are most relevant to a presentation if they? -provide excitement. -repeat a previous point. -support the content. -use biased viewpoints?

The correct answer is C. Support the content

Explanation:

Informational sources including books, scientific studies, statistics and news, and articles. In the case of media sources, this refers to the sources that communicate to the general public including news broadcasts, newspapers or radio programs and that can be used as part of a presentation to support and explain the ideas of an author.

However, for a source including a media source to be relevant, appropriate and credible the media source will need to be updated, which means the information should be recent; it needs to be relevant which means it addresses the same point of the speech; it needs to be written by experts which is usually common in media sources as they are regulated by experts and it needs to be accurate which can be identified by analyzing if the author provides support from the content and explains the source of it, which shows information relies on facts.

Considering this, it can be concluded media sources are most relevant to a presentation if they support the content because this shows the information is back up by scientific information or facts and this show the audience the information does not only support the ideas of the speaker but can be believed.

the underline word is basically like a prepositional phrase.
