A. Orient the audience

Explanation:

In presentations, visual cues are visual signs that include features such as color, movement, form, and depth to help the audience understand something by providing a visual sign or remind them of important content. On the other hand, in presentations transitions are words, phrases, symbols, sounds and any other used to help the audience understand the presenter is moving from one point to another, this includes changes in the discourse, a beginning of a new topic, transition in slides, graphic, images, and others. Thus, both visual cues and transitions help the audience to follow the speech of the presenter and understand the information by helping it to focus on the aspect the presenter wants the audience to focus, providing a visual aid that is easier to understand that speech and making clear when the speech moves or changes, in this way visual cues and transitions if used appropriately can orient the audience in a presentation.
