Final answer:
Organizing is one of the four principal functions of management, which are planning, organizing, leading, and controlling.
Step-by-step explanation:
The one function mentioned which is one of the four principal functions of management is Organizing. These four functions are essential in the management process and are commonly known as planning, organizing, leading, and controlling. Organizing is specifically the process of arranging resources and tasks to achieve the organization's objectives. Other actions like scheduling, motivating, executing, and monitoring are related to these primary functions, but they are not considered as one of the four principal functions themselves. Scheduling is a part of planning, motivating falls under leading, executing is about implementation, which may involve aspects of all four functions, and monitoring is related to the controlling function.
