Final answer:
Douglas McGregor is the person associated with the development of the Theory X and Theory Y model, which presents two opposing views of employee motivation and management styles. Hence, the correct answer is option (c).
Step-by-step explanation:
The individual associated with the development of the Theory X and Theory Y model is Douglas McGregor. These theories describe two contrasting models of workforce motivation and management. Theory X assumes that employees are naturally unmotivated and dislike work, which necessitates an authoritarian style of management. In contrast, Theory Y posits that employees are self-motivated and thrive on responsibility, which is best supported by a participative management style. McGregor's Theory X and Theory Y have significantly influenced management practices and the study of organizational behavior.
McGregor's purpose in presenting these theories was to highlight how different managerial assumptions about employees can influence management style, decision-making, and overall organizational climate. He advocated for Theory Y as a more effective and humane approach to management, emphasizing trust, employee involvement, and a positive view of human nature.
