Solution
The correct option is D Starfish
The water vascular system is a hydraulic system used by echinoderms, such as sea stars and sea urchins. It plays an important role in the locomotion, food and waste transportation, and respiration. The system is composed of canals connecting numerous tube feet. They move by alternately contracting muscles that force water into the tube feet, causing them to extend and push against the ground, then relaxing to allow the feet to retract.
Starfish or sea stars are star-shaped echinoderms belonging to the class Asteroidea. Hence, option D is correct.
