- C. Coelontorates
- D. Molluscs
Explanation
A rasping tongue-like radula with horny teeth is present in mollusks, particularly in the classes Gastropoda (snails and slugs) and Polyplacophora (chitons). The radula is a specialized feeding organ found in many mollusks, and it serves as a unique adaptation for grazing and consuming a variety of food sources. The radula is located within the mouth of the mollusk and consists of rows of tiny, chitinous teeth that are used for scraping and rasping food particles from surfaces.
