Which statement accurately describes a SDLC model?

1. The waterfall model emphasizes sequential development.

2. The iterative model emphasizes multiple passes through the same phase.

3. The spiral model emphasizes prototyping as part of the process.

4. All of the above.

The correct answer is: All of the above.

The statement that accurately describes an SDLC (Software Development Life Cycle) model includes all the points presented in the options. The waterfall model is known for its linear and sequential approach to software development, where each phase must be completed before the next one begins. This model is characterized by its structured format, making it easy to understand and manage. The iterative model focuses on creating a version of the software in a series of iterations or cycles. In each cycle, the development team revisits and refines components of the software based on user feedback and testing results. This approach allows for continuous improvement and adaptation to changing requirements. The spiral model integrates the concept of risk analysis into the development process and emphasizes the use of prototypes. It combines elements of both iterative and waterfall models, enabling teams to assess risks at each phase and create multiple prototypes before finalizing the product. Since each of these statements accurately reflects a fundamental aspect of the respective SDLC models, the correct choice encompasses all of these characteristics.
