What are mockups in graphic design?

Mockups in graphic design are visual representations that illustrate how a design will appear in its final form. They serve as an important tool for designers to communicate their ideas and concepts effectively. By creating a mockup, designers can showcase their work in a realistic context, such as how a logo will look on a business card, the layout of a web page, or how packaging will appear in a retail environment. This helps clients and stakeholders to visualize the end product, facilitating feedback and revisions before the final implementation.

The other options refer to different aspects of graphic design. Templates for digital illustrations are pre-made layouts or designs that can be filled in with custom artwork. Line drawings are more about the sketching or outlining of characters or objects without depth or color. Color palettes for branding consist of selected colors that define a brand's identity and visual presence, but they do not represent the mockup concept directly. Mockups specifically focus on presenting the design in its intended application, making option B the most fitting choice.
