Division of labour enhances firm efficiency via specialization

Steps:

• Define division of labour as assigning specialized tasks to workers for repetitive production.
• Identify advantages like higher productivity and cost savings from expertise.
• Evaluate options: A indicates worker dissatisfaction (disadvantage); B enables automation of routine tasks; C promotes generalism (opposite of specialization); D arises from monotony (potential drawback).
• Select B as it directly stems from repetitive tasks suiting machinery.

Why B is correct:

• Division of labour creates repetitive, standardized tasks that facilitate mechanisation, reducing costs and increasing output per Adam Smith's pin factory example.

Why the others are wrong:

• A: High labour turnover results from worker boredom, a disadvantage.
• C: Movement between tasks reduces specialization benefits.
• D: Quality control needs increase due to deskilling, not an advantage.

Final answer: B
