GInI’s CInP Handbook describes Design Methods as practical tools (e.g., journey mapping, prototyping) that operationalize Design Thinking’s principles. These methods enable teams to " study problems " (via empathy, observation) and " evaluate potential solutions " (via prototyping, testing), spanning the process from problem definition to solution validation. This dual focus is central to GInI’s human-centered approach, ensuring innovations address real issues effectively. Option B, " study users and trends, " is partial (users yes, trends less so). Option C, " markets and strategies, " shifts to business planning, not design. Option D, " markets and opportunities, " is market research, not Design Thinking’s core. Option A matches GInI’s intent, aligning with the original answer, embodying a systematic, problem-solution dialectic—a bedrock of GInI’s innovation practice.
