Solution
The correct option is C Tube-feet
A unique feature of echinoderms is their water vascular system. It is a complex system of tubes and bladders which carry water through pores in the skeleton. On the outside, these tubes look like feet. so, are called tube feet. These tube feet are used for locomotion, exchange of gases and feeding.
An earthworm moves using circular and longitudinal muscles, as well as bristles called setae. Pseudopodia is the locomotory structure in amoeba and cilia in paramoecium.
