Final answer:
The management function of selecting goals and future courses of action is closely related to the planning function of management.
Step-by-step explanation:
The management function that involves selecting goals and future courses of action and deciding how to achieve the desired results is most closely related to the planning function of management.
Planning is an essential management function that involves setting goals, identifying the actions needed to achieve those goals, and determining the resources required. It is the process of deciding what needs to be done and how it will be accomplished.
For example, if a company sets a goal to increase sales by 10% in the next quarter, the managers would need to plan and decide on the strategies and actions to achieve this goal, such as implementing marketing campaigns, improving product offerings, or expanding into new markets.
