Final answer:
In the phylum Cnidaria, jellies are members of the medusozoan clade and corals are members of the anthozoan clade. The correct answer is B. medusozoan; anthozoan
Step-by-step explanation:
Cnidarians are invertebrates such as jellyfish and corals. They belong to the phylum Cnidaria. All cnidarians are aquatic. Most of them live in the ocean. Cnidarians have radial symmetry and tissues. There are more than 10,000 cnidarian species.
The class Anthozoa includes all cnidarians that exhibit a sessile polyp body plan only. Examples include sea anemones, sea pens, and corals, with an estimated number of 6,100 described species. Sea anemones are usually brightly colored and can attain a size of 1.8 to 10 cm in diameter. These animals are usually cylindrical in shape and are attached to a substrate. A mouth opening is surrounded by tentacles bearing cnidocytes. The correct answer is B. medusozoan; anthozoan
