Answer: Option D

Prof. Robert Katz has divided managerial skills into three key skills: chiefly technical skills, conceptual skills, and human relation skills. These skills are essential for effective management and leadership within organizations. Technical skills involve the ability to perform specific tasks and procedures, conceptual skills involve understanding complex situations and abstract ideas, and human relation skills involve interpersonal communication, teamwork, and conflict resolution. Katz's framework provides a comprehensive understanding of the diverse skill sets required for managerial success.
