Which statement best describes a wireframe?

A wireframe is a low-fidelity representation outlining the layout of a page, which is essential in the early stages of the design process. It serves as a blueprint for the overall structure and functionality of a webpage or application, focusing on elements such as placement of text, images, and navigation links without delving into design details like color schemes or typography. This abstraction allows designers to communicate ideas clearly and make quick adjustments based on feedback, ensuring that the fundamental design principles and user flows are addressed before progressing to high-fidelity designs or prototypes.

The other choices do not accurately describe a wireframe. Detailed prototypes typically combine both functionality and aesthetics, moving beyond the basic structure that a wireframe provides. High-resolution versions of a final product represent completed designs and are not merely outlines. A marketing plan is unrelated to design and focuses on how to promote and launch a product instead of visual layouts or usability considerations.
