Amazon, a successful online retailer, manages an extensive customer database that is used to determine which products are suggested to each customer. Some data are best collected from the customer; other data are best collected from the businesses where purchases are made. Which of the following customer data are best collected from the customer A. Publicity B. Personal Selling

I think there is something missing in this question. We do not have enough statements to answer it.

B

Explanation:

Personal selling is a concept in which a sales representative deals with the customer directly as the case study suggested that Amazon is targeting customer according to his/her needs that is why the right option is B. not A publicity. As publicity is not directed towards a single customer's needs. It is generally done to target specific audience not the individual customer
