Max Weber's model "bureaucracy" helped in reducing favoritism and other unfair practices by:

A) assigning specific duties and responsibilities only on the basis of talent and ability.
B) assigning multiple supervisors to whom each worker must answer.
C) advocating careful selection and in-depth training of workers to motivate them.
D) implementing rules like standard work days, relaxed and regular lunch breaks, and rest periods.

Max Weber's bureaucracy model emphasizes the importance of selecting employees based on their skills and qualifications rather than nepotism, favoritism, or personal relationships. As a result, this minimizes unfair practices and promotes a merit-based system. Assigning specific duties and responsibilities solely based on talent and ability ensures that employees are chosen based on their performance and competence rather than other factors. Option B does not necessarily reduce favoritism, as having multiple supervisors may increase bias and conflicts. Option C, while important, primarily focuses on motivating workers rather than minimizing unfair practices. Option D addresses work conditions rather than the selection process for employees.
