Dunkin' Donuts is expanding in several different countries. Its stores offer curry doughnuts in India, dulce de leche doughnuts in Peru, and cherry brandy doughnuts in Germany. This is an example of segmentation based primarily on:

The correct answer is : geography.

The process of market segmentation involves dividing the market place so that the service or good the business wants to sell can reach many costumers at the same time. Otherwise without segmenting the market place it would be impossible to target so many costumers.

In this case, the company selling donuts has landed in different countries and it is selling its product taking into consideration geographic criteria.
