Correct answer: C
Concept
A process model should match the project’s dominant uncertainty. When users cannot clearly describe an unfamiliar interface in advance, an early interactive representation helps reveal usability needs and refine requirements through feedback.
Application
The intended users have no prior computer experience, so written requirements alone may not expose navigation, wording, and data-entry difficulties.
An early interface model lets those users perform representative tasks and identify confusing screens or controls.
Their observations can be incorporated in successive revisions before the full system is built.
Contrast
The spiral model emphasizes iterative risk analysis and risk reduction.
The component-based model emphasizes assembly from reusable components.
The waterfall model emphasizes sequential phases based on requirements established early.
Therefore, Prototyping is the most suitable approach for this project.
