Answer:
The correct answer is letter "B": A personal interest.
Explanation:
Businesses based on consumers' personal interests attempt to provide a tailored good or service. The competitive advantage of the organization relies on the uniqueness of the product they can provide to their clients compared to competitors who tend to offer products with wide features to cover the larger amount of needs possible.
Conducting businesses driven by customers' personal interests requires constant studies of consumer patterns to adapt in front of market changes and segmentation to identify what sector of the market the company will dedicate their efforts to.
