Marmagao Port is an important port in the country in terms of export of iron ore. It exports iron ore from Kudremukh mines, half (50 per cent) of the total exports of the country. New Mangalore Port located in Karnataka exports iron ore from Kudremukh mines. Kochi Port is in the far south-west; it is a natural harbour located at the mouth of a lagoon. Hence, all the three statements are correct.

Answer: A

Explanation:

Tuticorin port is located on the south-eastern tip of Tamil Nadu along the east coast. It is a natural harbour and has a very rich background. Hence, this port handles trade of various goods from our neighbouring countries like Sri Lanka, Maldives etc. and coastal areas of India. Hence, pair 1 is correctly matched.

Chennai is the oldest artificial port of our country. It ranks second after Mumbai in terms of volume of trade and goods handled. Hence, pair 2 is not correctly matched.

Kolkata is an inland riverine port. This port serves the large and rich background of the Ganga-Brahmaputra basin. Being a tidal port and the sediment deposition of Hooghly, it has to be cleaned regularly. Haldia has been developed as a subsidiary port to reduce the increasing trade at Kolkata Port. Hence, pair 3 is not correctly matched.

Answer: C

Explanation:

The exchange of goods between individuals in states and countries is called trade. The market is a place where this exchange takes place. This trade between two countries is called international trade. It can take place through sea, air and land routes. Although local trade takes place in cities, towns and villages, state-level trade takes place between two or more states. The progress of a country's international trade is an indicator of its economic prosperity. That is why it is also called the economic barometer of the nation. Hence, option (c) is correct.
