Correct Answer: Enhancing economic growth

Solution : The correct answer is (b) Enhancing economic growth

The primary purpose of transport infrastructure is to enhance economic growth. Transport infrastructure, such as roads, railways, airports, and ports, plays a crucial role in facilitating the movement of goods, services, and people. By providing efficient and reliable transportation networks, transport infrastructure enables trade, business activities, and economic exchanges. It connects producers with markets, allows the movement of raw materials and finished products, and supports various industries and supply chains. The development of robust transport infrastructure promotes economic integration, stimulates investment and productivity, and contributes to overall economic growth and development. While transport infrastructure can have secondary effects on employment, social equality, and the environment, its primary purpose is to facilitate and drive economic growth.
