Answer:
Correct Answer: C
Solution:
Urochordata does not have tunicin in its alimentary canal.
Tunicin is the external covering, surrounding the urochordates which is a leathery, translucent test or tunic composed of tunicin, a substance akin to cellulose of plants.
The foot is made entirely of test.
The test has a clear matrix in which are embedded cell of various shapes, interlacing fibrils, calcareous spicules and branching vascular vessels.
Because of the presence of such a tunic or test all over the body, it is known as tunicata.
