Verified By Collegedunia
The Correct Option is A
Solution and Explanation
The water vascular system is a unique hydraulic system found in echinoderms (starfish, sea urchins, etc.). It's primary functions are locomotion (via tube feet), food capture (also using tube feet), and respiration (gas exchange through tube feet and other structures). It plays a minor role in excretion, but its main roles are locomotion, feeding, and respiration.
