Solution

The correct option is C Assertion is correct but Reason is incorrect.
Echinoderms are the organisms which have disc shaped body. There are five arms which are also called as tube feet. Pedicellaria is a small wrench or claw-shaped structure. This is commonly found on the body of echinoderms. This structure is observed in sea stars and sea urchins. This organ helps to keeps the body surface clear of algae, encrusting organisms, and other debris. This structure works in association with the ciliated epidermis present in all echinoderms.
Thus, the correct answer is option C.
