Final Answer:
Layouts (Option C) are drawings that show what the print ad will look like and from which the final artwork will be produced.
Step-by-step explanation:
Layouts play a crucial role in the advertising design process. They are visual representations or drawings that depict the arrangement of elements in a print ad, including text, images, and other design components. These drawings serve as a blueprint for the final artwork that will be produced for publication.
Layouts provide a preview of the ad's visual composition, allowing stakeholders to review and approve the design before it goes into production. Options A (Creative briefs), B (Packshots), D (Art infusions), and E (Product sheets) are not specifically associated with the visual depiction and arrangement of elements in the context of advertising layouts.
Option C is the answer.
