Solution
The correct option is D Cnidaria
All animals that are more complex than sponges produce two or three primary tissue layers.
Animals with radial symmetry, like cnidarians, produce two layers called ectoderm and endoderm, making them diploblastic.
Animals with bilateral symmetry produce a third layer in-between called mesoderm, making them triploblastic.
