Which of the following is a type of prototype?

High-fidelity prototypes are highly detailed and closely resemble the final product in both appearance and functionality. They often include realistic elements, such as graphics, animations, and interactive features that enable stakeholders to experience the product as it will be in its completed form. This type of prototype is commonly used to gather user feedback on the design, test usability, and validate the overall concept before moving into full-scale production.

High-fidelity prototypes can be crucial for identifying potential issues or areas for improvement that may not be as easily detected in lower-fidelity prototypes, such as sketches or wireframes. By focusing on this level of detail, teams can ensure that they are not only building the correct product but also that it meets user expectations and needs effectively. This phase can significantly reduce costly revisions during later stages of development by resolving design issues upfront.

In contrast, other prototype options like high-functioning, middle-fidelity, and finalized are either not standard terminology or do not provide the same level of depth and realistic interaction that high-fidelity prototypes are known for.
