| Column I | Column II |
|---|---|
| A. Pleurobrachia | I. Mollusca |
| B. Radula | II. Ctenophora |
| C. Stomochord | III. Osteichthyes |
| D. Air bladder | IV. Hemichordata |
To solve this problem, we need to match the organisms and structures in List I with the correct phyla or classes in List II.Let's analyze each item:PleurobrachiaPleurobrachia is a genus of comb jellies, which belong to the phylum Ctenophora. Therefore, A matches with II CtenophoraRadula: - A radula is a structure used by mollusks for feeding, often described as a "tongue" with teeth. - Therefore, B matches with I Mollusca.
