Division of labour enhances efficiency but harms motivation

Steps:

• Division of labour splits tasks for specialization, raising overall output.
• It typically lowers costs, boosts productivity, and improves quality via expertise.
• However, repetitive tasks often cause boredom, reducing worker motivation.
• Thus, increased motivation is unlikely, making B the exception.

Why B is correct:

• Per Adam Smith's theory, division of labour creates monotonous routines that demotivate workers by limiting skill variety and job satisfaction.

Why the others are wrong:

• A: Specialization reduces average costs through economies of scale and efficiency gains.
• C: Focused tasks increase productivity by allowing faster, more skilled work.
• D: Expertise from repetition enhances precision and quality in the final product.

Final answer: B
