Correct answer: A
Answer: Waterfall model is the classic life cycle model.
Key idea: a linear sequence of phases where each phase must finish before the next begins.
Typical phases: requirements → design → implementation → testing → deployment → maintenance.
Works best when requirements are well understood and unlikely to change.
Why the other models are not the classic life cycle model:
RAD model: emphasizes rapid, iterative development and prototyping rather than a single linear pass through phases.
Prototyping model: builds prototypes and refines requirements through repeated cycles, making it iterative.
Incremental model: develops and delivers the system in multiple increments or releases, which is an iterative, phased delivery rather than one strict linear flow.
