Generative AI's defining characteristic is that it creates new content (text, images, code, summaries, drafts) in response to instructions---most commonly natural language prompts. Option C captures that general-purpose description in a stakeholder-friendly way: users provide prompts and the system generates responses or content. This framing is broad enough to cover common business value scenarios such as summarizing documents, drafting communications, creating marketing copy, generating reports, building assistants, and producing structured outputs from unstructured requests.
