Final answer:
Loyal customers are the most likely group to have high desire to repurchase, strong product preference, long customer history, and a very high referral value.
Step-by-step explanation:
The group of customers who are most likely to have high desire to repurchase, strong product preference, long customer history, and a very high referral value are loyal customers.
Loyal customers are those who consistently choose to repurchase a product or service from a particular brand or company. They have a strong attachment and preference for the brand and have built a long history of being a customer. These customers not only have a high desire to repurchase, but they also have a strong influence in referring others to the brand, leading to a very high referral value.
In contrast, the other options listed—unprofitable customers, captive customers, customer terrorists, and repeat customers—do not necessarily exhibit the same level of loyalty and commitment to the brand, which makes loyal customers the most likely group to have all the mentioned characteristics.
