Question
The sea stars and sea urchins use ______ to acquire their food.
Correct Answer
Option B is the correct answer.
Detailed Explanation
Sea stars and sea urchins are echinoderms, and they primarily use their tube feet (part of their water vascular system) for locomotion, attachment, and feeding. Baleen plates are found in baleen whales, a muscular pharynx in some flatworms, and oral suckers in some parasitic worms.
Hint
These structures are part of their unique water vascular system.
