A product owner is asked to justify why segmentation matters to the Product Backlog rather than only to marketing. What is the strongest answer?

• AIt does not, since segmentation is a marketing activity.
• BIt matters because it produces personas, which are needed for user stories.
• CIt matters because larger segments always justify more investment.
• DThe segment definition decides whose problems count as widespread enough to act on, which decides what gets ordered near the top, so changing the segment changes the backlog.
