Solution
The correct option is B Asteroidea
Pedicellariae is a small wrench- or claw-shaped structure commonly found on echinoderms, particularly in 'sea stars' (class Asteroidea) and 'sea urchins' (class Echinoidea). They are thought to keep the body surface clear of algae, encrusting organisms, and other debris in conjunction with the ciliated epidermis present in all echinoderms. Hence, option B is correct.
