Answer:
D) standardized marketing
Explanation:
Standardized marketing is most frequently used for convenience mass product, and the king of the world is Coke. Let's forget about the strange variations of Coke that some people like, Coke is number 1 in the world. it is sold virtually everywhere, and even in the places where it is illegal, like Cuba and North Korea, the presidents and rulers of those countries import Coke to drink it themselves.
Coke holds 17.3% of the soft drink market, and that is simply huge for a single product (in the US, all Coca Cola products hold 43.3% of the market). The fact that one product can be sold everywhere, using the same basic formula, ingredients and production processes is amazing.
Coke is the zenith of standardized marketing, since differences in culture, behaviors, socio-economic variables, nothing matters. Very few products or services have actually managed to achieve something similar, of course at a smaller scale, e.g. McDonald's, Walmart, , FB, etc.
