Division of labor increases productivity because tasks are specialized; however it can cause monotony.

• A. Increases productivity due to specialization, but can cause monotony
• B. Reduces productivity due to repetition
• C. Eliminates need for management
• D. Always raises wages in all sectors

Answer: (A)

Dividing work lets workers focus on a narrow set of tasks, so they become skilled at those tasks, performing them faster and with fewer errors. That specialization boosts overall output and efficiency, which is why productivity tends to rise. But doing the same routine tasks repeatedly can become monotonous, lowering motivation and job satisfaction, which can slow production or lead to mistakes if boredom grows. This combination—higher output from specialization, paired with the risk of monotony—is exactly what the statement captures.

The other ideas miss the key effect: repetition isn’t automatically a drag on productivity in the short run because practice speeds up work; management is still needed to coordinate tasks across workers; and wages don’t rise in all sectors simply because tasks are divided.
