Which of the following is a characteristic of the Evolutionary prototype?

The characteristic of the Evolutionary prototype that is most accurate is that refinement occurs through iterative feedback. This type of prototype is designed to evolve over time, based on input from users at various stages of development. Each iteration allows for enhancements and adjustments based on user experience and requirements, making it a dynamic process that continually integrates feedback to improve the software or system being developed.

In contrast to the other options, an Evolutionary prototype does not get discarded after use; rather, it serves as a foundation for further development. It also involves user input during the development process, which is essential for gathering requirements. Furthermore, it necessitates active user involvement to ensure that the evolving prototype aligns with user needs and expectations, rather than operating independently without user feedback. This iterative approach is crucial for creating a final product that is more likely to meet the needs and preferences of its users effectively.
