Final answer:
Decision making is a key component of the planning process in the basic management functions. It is where goals are set and resources are allocated. Equally distributing resources is not considered a main purpose of government in functionalism.
Step-by-step explanation:
When considering the basic management functions, decision making is most closely associated with the planning process. Planning involves setting goals and deciding on the actions required to achieve those goals. As a part of the planning process, managers must make decisions about the allocation of resources, the course of action to take, and how to best achieve the organization's objectives.
In response to the other question provided for context, which is not one of functionalism's four main purposes of government, the answer is (c) Equally distributing resources. While the functionalist perspective emphasizes the role of government in maintaining law and order, meeting social needs, and planning and directing society, equal distribution of resources is not typically listed as a main function of government from this theoretical viewpoint.
