Hint:What is coastline? This question will arise in your mind. A Coastline is an area where the land meets the sea or ocean. It acts as an exact boundary with the unmeasured perimeter between the land and the sea or ocean.

Complete answer:
According to the coastal line’s paradox, the exact length of the coastal line cannot be found since the landmass doesn't have a well-defined length. The measured coastline is an approximate length of the coastal line. The magnitude depends on the resolution of the instrument used for measurement.
Let us discuss the Indian Ocean which is the third largest ocean in the world with 20% of the water present on the surface. It is the only ocean named with the name of a country. It has an area of 6 million kilometres. It shares boundaries with seven seas. Pakistan has a coast length of 900 km. Sri Lanka is an island in Indian Ocean with a coastal length of 1340 km. The coastal length of Myanmar is 2300 km . India is surrounded by Arabian Sea in West, Bay of Bengal in East and Indian Ocean in south. Including the coastal length of island territories and mainland it has coastal length of 7561.6km. It is the country with the longest boundary on the Indian Ocean.

Hence, the correct answer is option (B).

Note:Indian coastline also consists of mangrove forest, Rivers, estuaries and ponds. Due to the large coastline of the ocean in India, it.is named as Indian Ocean. It helps to connect Western Europe with south East Asia and East Asia.
