Question

• A. Corals form branch colonies
• B. Corals are solitary or colonial
• C. Corals grow as massive bodies
• D. All of the above

Answer 1

The correct option is D All of the above

Corals belong to class of Anthozoa, which exist as solitary or colonial. Solitary forms remain as one polyp and one corallite. Colonial forms can reproduce the polyp asexually (cloning) and the new polyp forms another corallite that is attached to the first corallite. Corals are the rock like external skeletons. Coral animals secrete external skeletons of calcium carbonate.

Therefore, the correct answer is option D.
