In the Design Thinking process, the Prototype phase focuses on creating physical or digital models of ideas. This phase allows designers to experiment, explore possibilities, and turn abstract concepts into tangible products or solutions.
During prototyping:
Ideas are brought to life quickly and cheaply
Feedback can be gathered from users based on real models
Improvements and iterations are made before final production
Explanation of Other Options:
(B) Test: Evaluating prototypes to refine solutions.
(C) Define: Clarifying and framing the problem to be solved.
(D) Ideate: Generating ideas and brainstorming solutions.
Hence, the correct answer is (A) Prototype.
