Answer:
e. Country B, where education is well-developed and social stratification is lacking.
Explanation:
Country B will be the best option because the population is well-developed in terms of education, so there will be availability of skilled labour for the production plant.
Also lack of social stratification means there is no well-developed social stratification into upper, middle, and lower classes. Success will be due to individual achievement, so the people will be motivated to work hard and exploit the opportunity of growing in the new production plant.
