The correct option is D Inability to mobilise raw materials required for production
A versatile transportation system is the power of a country. An extensive network of transportation systems has been established through various means such as railways, roads, waterways, and airways. If there is no perfect transportation system, the country's development will be stagnant.
When a manufacturing company is deprived of its transportation system, all its operations are hampered. The raw materials necessary for production cannot be mobilised or sold outside the local market, and ultimately, it will affect the country's development. Without a transportation system, exporting goods is not even possible.
