A startup is developing a mobile app where user preferences are unclear and market conditions are rapidly changing. Requirements are expected to evolve significantly based on early user feedback. Which development methodology should they choose?

Agile because it accommodates changing requirements.

1. Relevant knowledge points and concepts
- Agile methodology: iterative, incremental development with short cycles (sprints), continuous user feedback, adaptable scope, and focus on working software and MVPs.
- Waterfall: linear, sequential phases (requirements → design → implementation → testing → deployment) that assume stable requirements.
- SDLC: a generic term for the Software Development Life Cycle, which can be implemented via different methodologies (Agile, Waterfall, etc.).
- Traditional Project Management (e.g., PMI-style): often emphasizes fixed scope, comprehensive planning, and change control, which can be rigid for evolving products.

2. Step-by-step reasoning
Step 1: Identify constraints — user preferences unclear and market conditions change rapidly.
Step 2: Requirements expected to evolve significantly based on early user feedback — implies need for frequent adjustments.
Step 3: Select methodology that supports rapid iteration, easy reprioritization, and close user feedback loops.
Step 4: Compare candidates — Agile directly supports frequent changes and early delivery of increments; Waterfall and traditional approaches do not fit an environment with high uncertainty.

3. Intermediate “steps” (conceptual)
- Start with an MVP to test hypotheses.
- Run short sprints to implement features, gather feedback, and reprioritize backlog.
- Use continuous integration and deployment to deliver updates quickly.

4. Why the correct answer is correct
Agile explicitly addresses evolving requirements through iterative cycles, prioritized backlogs, and close stakeholder feedback. For a startup where early feedback will drive major changes, Agile minimizes waste, shortens feedback loops, and lets the team pivot rapidly — matching the scenario.

5. Why other options are incorrect
- Waterfall (clear documentation): good for stable, well-defined requirements, not for rapidly changing startups.
- Waterfall (changes can be easily incorporated): incorrect — Waterfall makes changes costly and disruptive.
- SDLC (handles uncertainty well): SDLC is an umbrella term and does not specify adaptability; some SDLC implementations are waterfall-like.
- Traditional Project Management (faster): traditional methods tend to be slower to respond to change; speed is not inherent.

6. Conclusion
Therefore, Agile because it accommodates changing requirements is the correct choice, matching the provided answer.
