Which of the following is considered as the "Support system" on which depends the efficient working of a modern industrial economy?

Infrastructure

Infrastructure is the support system on which depends the efficient working of a modern industrial economy. Modern agriculture also largely depends on it for speedy and large-scale transport of seeds, pesticides, fertilizers and the produce using modern roadways, railways and shipping facilities. In recent times, agriculture also depends on insurance and banking facilities because of its need to operate on a very large scale. Thus, developed infrastructure is really important for the development of a country.
