Solution

The correct option is C Pila globosa
The radula is an anatomical structure in every class of molluscs except bivalves (Unio, clamps, oysters). Molluscs feed by means of a peculiar rasping tongue, called as radula. It is a tiny little chainsaw-like structure made up of chitin. It is present in Pila.
So, the correct answer is option C.
