Which of the following is true about iterative development?

Iterative development is characterized by its approach to integrating user feedback throughout the development process, making option B correct. In this method, development is broken down into iterations or cycles, where each iteration includes stages of design, coding, and testing. During these stages, user involvement is critical as it allows for the collection of feedback on the product's functionality and usability. This feedback can then be used to improve and refine subsequent iterations, ensuring that the final product better aligns with user needs and expectations.

In contrast, the first option is inaccurate because iterative development does not start with fully defined specifications; instead, it embraces evolving requirements. The third option misrepresents the process, as changes made during development are typically recorded to maintain clarity and manage the evolution of the product effectively. Lastly, the fourth option incorrectly asserts that iterative development is unsuitable for website development. In fact, iterative methodologies, such as Agile, are often employed effectively in web development projects to adapt to changing requirements and to incorporate user feedback incrementally.
