Henri Fayol's 14 Principles of Management include the principle of 'Unity of Command.' Which of the following BEST describes this principle? 

Fayol's principle of Unity of Command states that each employee should receive instructions from only one superior. This prevents dual authority, eliminates conflicting instructions, and fixes clear accountability. Option A describes Unity of Direction — which states that all activities with the same objective should be directed by one manager using one plan. Option C relates to the principle of Authority and Responsibility. Option D refers to Division of Work (specialisation). Option E refers to the principle of Equity. Distinguishing between Unity of Command (one boss per employee) and Unity of Direction (one plan for one goal) is a classic examination trap — the former relates to personnel, the latter to activities.
