Which sector is associated with information and knowledge-based support services such as ICT, consultancy and research and development?

• A. Tertiary sector
• B. Quaternary sector
• C. Primary sector
• D. Secondary sector

Answer: (B)

The key idea here is how economies are categorized by the type of activity. The quaternary sector covers knowledge-based activities that revolve around information, expertise, and innovation. ICT, consultancy, and research and development are all driven by specialized knowledge and produce value through ideas, analysis, software, and strategic advice rather than physical goods. That makes them a fit for the quaternary sector. By contrast, the primary sector involves extracting resources, the secondary sector focuses on manufacturing products, and the general tertiary sector encompasses broader services like retail and hospitality. So information and knowledge-based support services align with the quaternary sector.
