Tyrell recently noticed that he was receiving several catalogs and direct mail advertisements than he had in the past even though he had not requested any of them. Which of the following best explains why this is happening?
A. Tyrell was a victim of online theft.
B. Tyrell gave his personal information to a business, which then traded it to other companies and these companies then began sending him catalogs.
C. All businesses routinely have all customers' personal information.
D. Tyrell's accountant gave his information to the direct mail marketers.

In this particular scenario, the most likely occurrence is that Tyrell gave his personal information to a business, which then traded it to other companies and these companies then began sending him catalogs. Most companies online tend to gather as much private information from their customers and eventually sell that information to larger corporations that use it in order to increase their sales. This is done in many forms such as finding out what a client population likes and dislikes, how much money they spend, day to day activities, etc. All this information allows corporations to target specific individuals, and advertise directly to them in order to make sales.
