    Correct Answer is option (C). The radula is an anatomical structure used by mollusks for feeding, sometimes compared to a tongue.It is a minutely toothed, chitinous ribbon, which is typically used for scraping or cutting food before the food enters the esophagus. The radula is unique to the mollusca which instead use cilia, waving filaments that bring minute organisms to the mouth. Food particles are trapped into this sticky mucus, smoothing the progress of food into the oesophagus. Certain gastropods use their radular teeth to hunt other gastropods and bivalve molluscs, scraping away the soft parts for ingestion

    Correct Answer is option (C). The shape and arrangement of the radular teeth is an adaptation to the feeding regimen of the species. The teeth of the radula are lubricated by the mucus of the salivary gland, just above the radula. Food particles are trapped into this sticky mucus, smoothing the progress of food into the oesophagus.
