How do India's island groups affect the length of coastline?

Answer and explanation

Correct answer: They increase the total coastline

The governing concept is the measurement of total coastline. A country’s total coastline includes the shoreline of its mainland as well as the shorelines of its offshore islands. India’s Andaman and Nicobar Islands in the Bay of Bengal and Lakshadweep in the Arabian Sea each possess their own coasts. When these island shorelines are added to the mainland shoreline, the measured total becomes longer. Therefore, option A is correct. Islands do not make the coastline zero, and their effect is not limited to increasing a land boundary. Option D is also incorrect because every island has a shoreline where land meets seawater. The distinction between mainland coastline and total coastline is important.
