The correct answer is: If both assertion and reason are true and reason is the correct explanation of assertion.
Coral reefs are formed through the accumulation of calcareous exoskeletons of coral animals, calcareous red algae and molluscs. They form the foundation of reefs by secreting a calcium carbonate skeleton that provides protection for the coral polyps.
