Hint: A super ocean is defined as an ocean that surrounds a supercontinent.
Following the first clue, some of the given options can easily be discarded as they did not surround super continents.Some of the given options can easily be crossed out as they are not even water bodies.

Complete answer:
 India has an extended coastline which has numerous ports. Among all the ports, seven are designated as major ports. These ports are very important in India's trade and economy as most of the international trade is carried out through sea transportation. India has strong trade relations with many countries all over the world, and both imports and exports various materials. Let us see what each of the given ports primarily exports to find the correct answer.

A. Kochi is a port on the south western coast of India. It primarily deals with export of spices and marine products. Therefore, this is not the correct answer.

B. Paradip is a port on the east coast of India in Orissa. It mostly exports iron ore along with the ores and alloys of other metals as well. But is not the port accounting for 50% of iron ore exports. Thus, it is not the correct answer.

C. Marmagao is the premier iron-ore exporting port of India. This is because of its strategically advantageous location in the West coast. It facilitates faster export to the European countries. So this is the correct answer.

D. Haldia port is situated on the east coast of India. It mainly exports coal, steel and iron ore. Thus, this is not the correct answer.

Thus the correct answer is option ‘C’.
