The primary advantage of using prototypes in software development is that they allow for early modifications based on user feedback. Prototyping facilitates an iterative development process where a working model of the software is created early in the project. This model can be tested by users, enabling them to interact with the software and provide insights and suggestions that reflect their needs and preferences.

When feedback is gathered during the prototyping phase, developers can make timely adjustments to the software before it is fully built. This adaptation can significantly enhance user satisfaction and ensure that the final product aligns more closely with user expectations. Incorporating user feedback early in the design process tends to lead to fewer costly changes after full development, ultimately saving time and resources.

In contrast, while other options might touch upon aspects of software development, they do not capture the unique and critical role of prototypes in bridging the gap between user needs and development effort. For example, prototypes do not eliminate the need for user feedback, as engaging users is essential for understanding requirements and refining the product. Additionally, while prototypes might reduce certain testing timeframes, they primarily serve to refine and adjust the design based on real user interactions. Furthermore, they may not necessarily be less expensive than fully developed products, especially when considering the resources required for
