Why are the mainland and islands viewed separately while understanding India's total coastline figure?
Answer and explanation
Correct answer: Because island coastlines add extra length to the total figure
Option A is correct because the total coastline is obtained by considering the coastline of the mainland together with the coastlines of India’s islands. Islands have their own shores, bays, inlets, and coastal curves, so their lengths add to the national total rather than replacing or reducing the mainland coastline. The mainland itself has a long coastline along the Arabian Sea, the Indian Ocean, and the Bay of Bengal. Coastline is a length and is expressed in kilometres, not square kilometres, which measure area. Therefore, separating mainland and islands helps explain why the total coastline is greater than the mainland figure alone.
