The question asks us to identify which of the provided options is a principle by Henri Fayol, a French engineer and director of mines who developed a general theory of business administration. Among the options provided, Henri Fayol is known for his 14 Principles of Management. Let's analyze the options:
- Cooperation, not Individualism: This is not one of Fayol's principles; rather, it is associated with Frederick W. Taylor's scientific management principles.
- Scalar Chain: This is a principle by Fayol. The Scalar Chain refers to a clear line of authority in the organization that runs from top to bottom and should be followed in decision-making processes to maintain order and communication.
- Functional Foremanship: This is another concept related to Taylor's scientific management, not Fayol.
- Method Study: This is a technique used in scientific management for analyzing methods to increase productivity, not a principle by Fayol.
Based on this analysis, the correct answer is the Scalar Chain, as it directly corresponds to one of the principles articulated by Henri Fayol.
