Answer:
The answer is: B) concentrated/niche marketing
Explanation:
Niche (or concentrated) marketing concentrates all of its actions and promotions on small but very specific and well defined segments of the population. A niche marketing strategy focuses on becoming a big fish on a small pond, and usually charging a higher price for the niche product. The specific needs and requirements of those "niche customers" are usually not well addressed by mass marketing actions.
