Final answer:
The correct option is D. The criteria for a useful segmentation in business does not include profitability.
Step-by-step explanation:
The criteria for a useful segmentation in business does not include the option D) Profitable. While profitability is an important consideration in business, it is not specifically mentioned as one of the criteria for a segmentation to be useful.
A useful segmentation in business must be achievable (realistic, attainable, barriers could be overcome), identifiable (clearly define and distinguish the segments), substantial (segments must be large enough to be profitable), and accessible (segments must be reachable through marketing efforts).
In summary, the answer is D) Profitable is not among the criteria for a useful segmentation in business.
