Question

Role of the water vascular system in Echinoderms is: A. Respiration and Locomotion, B. Excretion and Locomotion, C. Capture and transport of food, D. Digestion and Respiration, E. Digestion and Excretion.

Choose the correct answer from the options given below:

1. A. A and B Only
2. B. A and C Only (Correct answer)
3. C. B and C Only
4. D. B, D and E Only

Correct Answer

Option B — A and C Only

Detailed Solution & Explanation

The correct answer is A and C Only.

Key Points

• The water vascular system in echinoderms helps in locomotion, capture and transport of food, and respiration — so A (respiration and locomotion) and C (capture and transport of food) are correct.
• Echinoderms have no excretory system (excretion occurs through the general body surface), so options involving excretion are wrong.
