The correct answer is B. The way immigration and emigration trends strengthen global relationships
Explanation:
In sociology, the Functionalist theory is a theory that states elements in society have a specific function and serve for a purpose. Because of this, in relation to immigration, emigration and demographical changes functionalist theories do not aim at understanding the process in which this occurs, the impact on population or the interaction this implies but the purpose of these elements in relation to social stability including the way immigration and emigration contribute to society or the way this create dysfunction. Therefore, a functionalist would address the way immigration and emigration trends strengthen global relationships, because this issue focuses on the stability of society in terms of global relationships which is the point Functionalists focus on.
