Answer 1

Hint: All species are aquatic, and Phylum Cnidaria 's mainly marine are predominantly categorised based on the dominance of the medusoid or polypoid process in the life cycle.

Complete answer:
> Option A is incorrect. Gorgonia or Sea fans look very much like plants with bright, forked "branches," but in fact they are animals. Meandrina or Brain Coral (a form of stony coral) in the Mussidae is the common name for a variety of coral species. The group of aquatic, predatory animals of the order Actiniaria are Adamsia or Sea anemones. They are named after a terrestrial flowering plant, the anemone. The Portuguese man o 'war (Physalia physalis), is a marine hydrozoan found in the Atlantic, Indian, and Pacific Oceans. It is also known as man-of-war, blue bottle, or floating terror.

> Option B is incorrect. The Portuguese man o 'war (Physalia physalis), is a marine hydrozoan found in the Atlantic, Indian, and Pacific Oceans. It is also known as man-of-war, blue bottle, or floating terror. Gorgonia or Sea fans look very much like plants with bright, forked "branches," but in fact they are animals. Meandrina or Brain Coral (a form of stony coral) in the Mussidae is the common name for a variety of coral species. The group of aquatic, predatory animals of the order Actiniaria are Adamsia or Sea anemones. They are named after a terrestrial flowering plant, the anemone.

> Option C is correct. Often recognised as the Portuguese war man, Physalia is a marine hydrozoan found in the Atlantic, Indian and Pacific Oceans. Meandrina is a colonial stony coral genus within the Meandrinidae family. Gorgonia is a genus in the Gorgoniidae family of soft corals, sea fans. In the family Hormathiidae, Adamsia is a genus of sea anemones.

> Option D is incorrect. Meandrina or Brain Coral (a form of stony coral) in the Mussidae is the common name for a variety of coral species. Gorgonia or Sea fans look very much like plants with bright, forked "branches," but in fact they are animals. The group of aquatic, predatory animals of the order Actiniaria are Adamsia or Sea anemones. They are known for the terrestrial flowering plant, the anemone. Physalia physalis (Portuguese man o 'war), is a marine hydrozoan found in the Atlantic, Indian and Pacific Oceans. It is also known as man-of-war, blue bottle, or floating terror.

Hence, The correct answer is option (C).

Note: The bodyform is diploblastic, radially symmetrical and has no coelom. The body has a single opening, the hypostome, surrounded by sensory tentacles that are either fitted with nematocysts or colloblasts to trap mainly planktonic prey. They have two membrane layers, between which there is a jelly-like mesoglea.
