Answer:
The correct answer is letter "B": product extension.
Step-by-step explanation:
In International Business, product extension refers to the approach by which a firm introduces its product or service across borders without shaping the product according to the profile of each consumer in each region. Product extension is implemented to expand the business operations of a firm in an attempt of finding new consumers in new markets, thus, generating more profit.
Product extension is likely to work only if customers' preferences and necessities are the same in different countries.
