D

Answer to Question 2

Marketers appeal to different social classes in different ways. For example, people who come from rich family backgrounds seek exclusivity in their brands. They may become less likely to buy a brand if a company produces less expensive product lines. Those who are nouveau riche tend to make purchases to show off that fact. For example, they may buy a bright red Ferrari to show off their new wealth.
