Ans-The answer is the option (c), Fasciola is a pseudocoelomate animal.
Explanation:
Fasciola is an acoelomate animal. Fasciola is not a pseudocoelomate animal as it does not possess a body cavity, and hence, it is an acoelomate.
Mesoglea is an undifferentiated layer and is a characteristic of diploblastic and triploblastic animals present along with ectoderm and endoderm.
Asterias shows a type of symmetry called radial symmetry. A Symmetry in which the body can be divided into two equal, identical halves from any plane passing through
the central axis.
Taenia is a triploblastic animal as it possesses three germinal layers, i.e., ectoderm,endoderm, and mesoderm.
