Solution
The correct option is B Pseudocoelomate - Platyhelminthes
The true coelom is the body cavity formed during embryo development. The coelom is lined by mesodermal epithelium. Animals which possess a body cavity are called coelomate e.g., annelids, molluscs, arthropods, echinoderms, hemichordates and chordates.
If the body cavity has scattered pouches in between the ectoderm and endoderm instead of the lining by mesoderm, then such a body cavity is called pseudocoelom and the animals possessing it are pseudocoelomates, e.g., aschelminthes.
The animals where the body cavity is absent are called acoelomates, e.g., platyhelminthes.
