Show answer & explanation
Correct answer: C
Answer: The correct selection is the one that includes both "Do we change requirements quite often?" and "Requirements are indicating a complex to be built".
Why the Spiral Model fits these characteristics:
The Spiral Model is iterative and risk-driven, making it suitable when requirements are likely to change frequently because each iteration revisits requirements and design.
It focuses on risk analysis and mitigation each cycle, so it handles complex or high-risk projects where unknowns must be explored and reduced gradually.
Why the other characteristics do not indicate the Spiral Model:
If requirements are easily understandable and can be defined early, plan-driven models (such as Waterfall) are usually more appropriate because they assume stable requirements and a linear development flow.
Summary: Choose the option that combines frequent requirement changes and high complexity/risk, because the Spiral Model's iterative, risk-focused approach addresses both needs.
