Coral reefs in India are found only in limited locations along the mainland; despite India has a huge coast. Which among the following is most correct reason for that?

Answer: [C] Presence of major river systems

In India, Coral reefs occur along only a few sections of the mainland, such as  Gulf of Kutch, off the southern mainland coast, and around a number of islands opposite Sri Lanka. Coral reefs are not found mostly on either side of southern Peninsula mainly because of presence of major river systems and the sedimentary regime on the continental shelf.
