Solution
The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
In echinodermates, the ring canal on its inner side gives off small irregularly shaped bodies which are known as the tiedemann's bodies. They are in five pairs. The function of these bodies is to produce coelomic corpuscles to dispose off bacteria which are released into the ring canal and so the system is known as water vascular system.Hence, the correct option is 'Both assertion and reason are correct and reason is the correct explanation of assertion'.
