What does a low-fidelity prototype typically lack?

A low-fidelity prototype typically lacks detailed design elements, which is why this choice is correct. Low-fidelity prototypes are often created using simple materials such as paper or basic digital tools, focusing on the overall concept rather than the finer points of design. Their purpose is to convey the basic ideas and flow of a user interface or interaction without the distraction of aesthetic details.

These prototypes prioritize usability and functionality concepts, allowing designers and stakeholders to discuss and iterate on ideas without getting bogged down by specifics like color schemes, fonts, or intricate graphics. Therefore, while they may provide a clear layout or represent certain functionalities, they do not include detailed design elements that would be present in higher-fidelity prototypes.
