Answer:

The correct option is #2 - "a series of deliverables produced during different phases." The waterfall model is a linear sequential approach where the development progresses through a series of phases, each preceding phase must be completed before the next phase can begin. Each phase produces deliverables, which are then used as inputs for the next phase. It is a document-driven approach, where requirements, design, implementation, testing, and maintenance are each treated as separate stages. Options 1, 3, 4, 5, and 6 do not accurately describe the waterfall model.
