Best answer

Answer: 2. A and C Only

Key idea: The water vascular system of echinoderms (tube feet) works in locomotion, capture and transport of food, and respiration.

A (respiration and locomotion) and C (capture and transport of food) are right. Excretion is not its role, and digestion is done by the alimentary canal. Option 2.
