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.

Explanation:

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

b. a single paragraph.

a paragraph is a series of sentences that are organized and make sense, and are all related to a single topic . almost every piece of writing you do that is longer than a few sentences should be organized into paragraphs. this is because paragraphs show a reader where the subdivisions of an essay begin and end, and thus the reader see the organization of the essay into subjects in order to be able to understand its main points.
