Expert Solution
Step 1
Step 1
Gastropods are commonly known as snails and slugs, belonging to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda. Gastropoda is the largest class of the phylum Mollusca, which possesses several different traits.
Step 2
Step 2
Gastropods have a buccal cavity with a toothed rasping organ, a chitinous ribbon, called a radula. This anatomical structure is used by mollusks for scraping or cutting off food, before the food entering the esophagus. It is used for feeding and is sometimes compared to a tongue. Therefore, option (c), a structure that aids in feeding is the correct answer.
