The correct option is C. there is a greater risk of unemployment. Detailed Explanation Understanding Division of Labour: Division of labour refers to the process of breaking down a production process into smaller, specialized tasks, where each worker focuses on a specific task. This method is widely used in manufacturing and service industries to increase efficiency and productivity. Why Option C is Correct: 1. Increased Specialization: When workers are assigned specific tasks, they become highly specialized in those tasks. While this can lead to increased productivity, it also means that workers may become less versatile. If the demand for a specific product decreases or if a company decides to automate a task, those specialized workers may find themselves without jobs, leading to higher unemployment rates in certain sectors.

1. Economic Vulnerability: In an economy where division of labour is prevalent, a downturn in a specific industry can disproportionately affect workers who are specialized in that area. For example, if a factory that produces a specific type of product closes down, the workers who only know how to perform their specialized tasks may struggle to find new employment in different sectors.
2. Skill Obsolescence: As technology evolves, the skills that workers have acquired through specialization may become outdated. If workers are not trained in a variety of skills, they may find it difficult to adapt to new job requirements, leading to unemployment.

Why the Other Options are Wrong or Weaker: A. There is saving of time - Explanation: This statement is true in the context of division of labour. By breaking down tasks, workers can perform their specific roles more quickly and efficiently, leading to time savings in production. Therefore, this option does not represent a disadvantage of division of labour. B. It results in workers acquiring greater skill at their jobs - Explanation: This statement is also true. Division of labour allows workers to become experts in their specific tasks, which can lead to greater skill acquisition. This is a benefit rather than a disadvantage, as it enhances productivity and efficiency. D. It makes possible the use of machinery - Explanation: This statement is accurate as well. Division of labour often facilitates the use of machinery, as tasks can be designed to be performed by machines or can be more easily automated. This is a benefit, as it can lead to increased production capacity and lower costs. Summary of Key Points:

• Division of labour can lead to greater specialization, which increases productivity but also creates a risk of unemployment if demand shifts or if tasks become automated.
• Specialized workers may struggle to find new employment if their skills become obsolete or if their specific industry declines.
• The other options (A, B, D) highlight benefits of division of labour rather than disadvantages.

Revision Summary:

• Division of labour increases efficiency but can lead to unemployment risks.
• Specialization may result in skill obsolescence and economic vulnerability.
• Benefits of division of labour include time savings, skill acquisition, and facilitation of machinery use.
