Option 1 -> Henry Fayol developed 14 principles of management, with "Division of Work" being the first principle.
Option 2 -> Henry Lawrence Gantt is known for developing the Gantt chart and contributions to scientific management, not division of work principle.
Option 3 -> Frederick Taylor is the father of scientific management, focused on efficiency and time studies, but didn't formally propose division of work as a principle.
