(a)Corals
(b)Red corals
(c)Sea anemones
(d)Jellyfish

Answer 1

Hint Sea flowers belong to the phylum Cnidaria and are found to exist in the polyps form attached to rocks or coral reefs waiting for fish to pass through close enough to catch them in their venom-filled tentacles.

Complete Answer:
Sea flowers are the common name for the animals which are known as sea anemones. Sea anemones are aquatic marine animals that are predatory in nature belonging to the order Actinaria, They are named after a terrestrial flowering plant called anemone because both of them have a colorful appearance. The bodies of sea anemones are composed of an adhesive pedal disc, foot, cylindrical body, and a mouth around which tentacles are projecting out. These tentacles are used in defense as well as in catching prey as it sends a paralyzing neurotoxin into the victim that slightly touches these tentacles.

Additional information:
Let us know more about cnidarians.
Members of Cnidaria are aquatic (mostly aquatic) with radially symmetrical bodies that are diploblastic with tissue level of organization.
These animals possess cnidoblasts or cnidocytes which are stinging capsules used for hunting prey or in defense or even anchorage. Hence these animals are called cnidarians.
Another characteristic feature of Cnidaria is the presence of a central gastro-vascular cavity with a single opening.
Cnidarians have two basic body forms known as a polyp which is a sessile and cylindrical form like Hydra, Adamsia, and medusa which is a free-swimming and umbrella-shaped form like Aurelia, jellyfish, etc.
Common examples of cnidarians include Physalia, Adamsia, Pennatula, Gorgonia, etc.

So, the correct option is ‘Sea anemones’.

Note:
-Some cnidarians like Obelia show alternation of generations which means that their polyp form produces medusa asexually and medusa form produces polyp form sexually.
-Sea anemones show a relationship with the hermit crabs known as commensalism.
-Commensalism is a type of relationship in which one organism benefits but the other one is neither benefited or harmed.
