Correct Answer: C
Solution :[c] Coral reefs are diverse underwater ecosystems held together by calcium carbonate structures secreted by corals. Most reefs grow best in warm, shallow, clear, sunny and agitated waters. Often called "rainforests of the sea", shallow coral reefs form some of the most diverse ecosystems on Earth. They occupy less than 0.1% of the world's ocean surface, about half the area of France, yet they provide a home for at least 25% of all marine species.
