An advertisement for a new model of luxury sedan would target
a) new drivers
b) families
c) professional adults
d) businesses

C. Professional adults.

The typical buyer of a luxury sedan is someone who has a steady stream of income and little need for a larger vehicle. Professional adults are usually secure in their careers and have a steady stream of income. Typically professional adults are seen as having white collar occupations and do not need a vehicle that requires a large carrying capacity.
New drivers are usually targeted with more economic cars because they are typically young and do not have the budget for a luxury sedan. Also families are not the likely target, since families usually are targeted for SUVs and Minivans which have more carrying capacity. Businesses are usually also targeted for vehicles with a bigger carrying capacity such as trucks and SUVs.
