Final answer:
KFC customizes its menu in Japan as a strategy of adaptation to meet local tastes, which is a common practice in global business to ensure market success. McDonaldization offers increased availability of goods but also leads to a reduction in variety. 'Transformation' is not one of the established four pillars of food security.
Step-by-step explanation:
The primary function of KFC's Japanese menu modification is B. Adaptation. This process involves altering the menu to better suit the local tastes and preferences of the Japanese market. Adaptation strategies in global business models, such as the ones used by KFC in Japan, are essential for multinational corporations to respect and respond to cultural differences and local consumer behaviors.
Moving on to the concept of McDonaldization, one advantage of this societal change is c. There is more worldwide availability of goods. However, a disadvantage is that a. There is less variety of goods. The term 'McDonaldization' describes the spread of the fast-food model to other industries, creating efficiency and uniformity but also potentially leading to homogenization.
As for the four pillars of food security, the correct answer is D. Transformation, which is not considered one of the pillars. The four pillars of food security are actually Availability, Access, Utilization, and Stability.
