Answer 2

Answer:

A - 'Great Barrier Reef' is the correct answer.  

Explanation:

It is because we know 'Coral polyp' is a tiny, soft-bodied creature which is related to 'sea anemones' and 'jellyfish'. At the base, there is a 'hard, protective skeleton' made of limestone which is known as calicle, which mainly forms the 'structure of coral reefs'.  

Reefs are formed again when a 'polyp attaches itself to a rock' on the seafloor, then 'divides, or buds', into 'thousands of clones'.
