Answer:
The correct option is option D, that is A set of buyers sharing the common needs or characteristics that the company decides to serve.
Step-by-step explanation:
The concept of target market is termed as the group of potential customers to whom a company wants to sell its products and services. This group also includes specific customers to whom a company directs its marketing efforts.
Thus

Option B is not correct as it is a the market coverage strategy which targets several segments of the market.
Option C is not correct as it is a method of effective marketing.
So only option D is correct.
