Which of the following sector is knowledge oriented?

The correct answer is Option 4: Both 2 and 3

• Quaternary Activities ➔ Knowledge-based activities like research, information technology, financial consultancy, education, etc.

• Quinary Activities ➔ High-level decision-making, policy formulation, top executives, and highly specialized knowledge-based services (like CEOs, government officials, researchers).

Thus, both Quaternary and Quinary activities are knowledge-oriented sectors.

• Tertiary Activities ➔ These provide services (like transport, trade, communication) but are not specifically knowledge-based.
