Design Thinking is a user-focused method for creative problem-solving, structured into five distinct phases. These phases are Empathize, Define, Ideate, Prototype, and Test. The initial phase, Empathize, involves understanding user needs through research and observation to establish a solid basis for problem definition. The final phase is Test, where prototypes or solutions are evaluated with users to collect feedback and refine the product or concept. This iterative process can be repeated until user needs are fully satisfied. Note that Prototype is the fourth stage, preceding Test, and is not the final stage. Consequently, the first and last stages are Empathize and Test, respectively. The correct option is (A) Empathize, Test.
