Correct Option: (B) Waterfall Model

Explanation

The Waterfall Model is a linear-sequential life cycle model. It is most effective when the project requirements are fixed, clearly defined, and stable from the beginning.

• Why it fits: In this model, each phase must be completed before the next one begins. Since there is no expectation of requirement changes, the project can follow a straightforward path:

  $$Project\_Flow=Requirement\to Design\to Implementation\to Testing\to Deployment$$

• Characteristics: Because it lacks feedback loops for frequent changes, the efficiency of the project can be represented as:

  $$Efficiency=f(Stable\_Requirements)$$

  If requirements are stable, the Waterfall model minimizes overhead and provides a clear structure for documentation and milestone tracking.
