Correct Answer

(A), (B), and (C) only

Rivers, canals, lakes and coastal areas have been important waterways since time immemorial.
Boats and steamers are used as means of transport for cargo and passengers. The development of inland waterways is dependent on the navigability width and depth of the channel, continuity in the water flow, and transport technology in use.
Rivers are the only means of transport in dense forests. Very heavy cargo like coal, cement, timber and metallic ores can be transported through inland waterways. In ancient times, riverways were the main highways of transportation as in the case of India.
But they lost importance because of competition from railways, lack of water due to diversion for irrigation, and their poor maintenance.
Transport and trade has been recognised throughout the developed world.
Despite inherent limitations, many rivers have been modified to enhance their navigability by dredging, stabilising river banks, and building dams and barrages for regulating the flow of water.
