When it comes to embryonic tissue layer in animals, some have two while some have three. Those with two layers are diploblastic while those with three layers are said to be triploblastic.

Body cavity evolution also vary in animals according to their development levels. Some animals lack body cavity totally and are referred to as acoelomates, some have a mesoderm-like fluid filled cavity and are referred to as pseudocoelomates while others have true body cavity with peritoneum and are referred to as coelomates.

During embryonic development, the mouth is formed first in some animals and they are referred to as protostomes while those in which the anus are formed first are referred to as deuterostomes.

<em>Hence, the best terms that describe the animal in question are triploblastic, pseudocoelomate, protostome.</em>

The correct option is A.
