Question

in which class is the radula utilized for food scraping?
gastropods
cephalopods
arthropods

Explanation:

Gastropods (like snails, slugs) use the radula for scraping food (e.g., algae off surfaces). Cephalopods (e.g., octopuses, squids) have a beak - like structure, not a radula for scraping. Arthropods have mouthparts like mandibles, not a radula. So the class where the radula is used for food scraping is Gastropods.

Answer:

A. Gastropods
