Show answer & explanation
Correct answer: C
Correct answer: Waterfall Model.
The Waterfall model is the classic linear SDLC model: requirements, design, implementation, testing, deployment, and maintenance move in sequence.
A later phase normally starts only after the previous phase has been completed and approved, so it matches the phrase “sequential flow”.
Iterative or incremental models may revisit work or deliver in cycles, so they do not match the strict phase-by-phase description as directly.
