Final answer:
The correct option is b). Henri Fayol's belief in the right of managers to give orders aligns with the principle of hierarchy of authority, closely tied to the scalar chain, where each level of an organization has clear reporting lines and responsibilities.
Step-by-step explanation:
Henri Fayol's belief that managers should have the right to give orders is best reflected in the principle of hierarchy of authority, which is not directly listed among his original 14 principles but is closely related to the concept of scalar chain. This principle emphasizes a clear chain of command within an organization, wherein each individual or office has a superior from whom they receive orders and to whom they are accountable.
For instance, in a retail environment like Walmart, an employee would receive directions from a shift manager, who in turn is responsible to the store manager, and the structure continues up to the CEO and board members. Fayol's principles were designed to improve management efficiency and ensure a unified direction for all employees.
