Answer:

d. They are both asymmetrical. Placozoans have endoderm and ectoderm while sponges have no tissue.

Explanation:

Placozoans and sponges are both animals with asymmetrical body plans. They differ in that placozoans are slightly more complex than sponges because placozoans have embryonic tissue layers: endoderm and ectoderm. Sponges have no tissue.
