Explanation:

List I	List II
A. Pleurobrachia	II. Ctenophora
B. Radula	I. Mollusca
C. Stomochord	IV. Hemichordata
D. Air bladder	III. Osteichthyes

Pleurobrachia is a member of the Ctenophora phylum. In molluscs, the radula is a rasping organ that resembles a file. Similar to the notochord, the stomochord is a rudimentary structure found in the collar region of hemichordates. Osteichthyes have an air bladder that keeps them buoyant.
