Step-by-step explanation:
The correct answer to the question about the value chain is D. Administration. The value chain is a concept that describes the full range of activities that companies engage in to bring a product or service from conception to delivery and beyond.
These activities include design, marketing, and customer service, which are all considered part of the value chain as they add value to the product or service. In contrast, administration is generally seen as overhead or support to these activities rather than a direct part of the value creation process.
