Concept:Process writing is a teaching method where writing is seen as a step-by-step development from basic ideas to a finished piece.Explanation:This approach starts with brainstorming and outlining. Then comes drafting, revising, editing, and finally publishing. Each stage builds on the previous one, moving from simple thoughts to complex, polished writing. It focuses on the individual steps and gradually improves the overall work. Unlike a single-direction approach (top-down or horizontal), process writing begins with the foundation and works upward. This makes it a bottom-up method. Writers learn by practicing each stage, refining their work through multiple cycles.Answer:The correct answer is bottom-up approach (Option C).
