If you are a diploblastic animal, you have: A. mesoderm. B. radial symmetry. C. a coelem. D. a mouth that developed from the blastopore. E. all of the above

C. Radial Symmetry

Explanation:

Diploblastic Animals are those animals whose blastula have basically two primary germ layers. These layers are called the endoderm and the ectoderm. On the contrary, most other animals have three layers found in them. The endoderm is an embryonic germ layer that gives rise to the gut. They also give rise to the tissues that form the internal organs. On the other hand, the ectoderm produces skin and nervous tissue and does cover the outside of the embryo. This type of body plan is particularly seen in cnidaria and ctenophora
