Read the following statements and choose the correct option.
A) In pseudocoelomates, body cavity is not lined by mesoderm and mesoderm is present as scattered pouches in between the ectoderm and endoderm.
B) In arthropods, body can be divided into identical left and right halves in only mid sagittal plane.
Arthropods exhibit bilateral symmetry. The body of arthropods can be divided into identical left and right halves by a mid-saggital plane.
In aschelminthes, the body cavity is not lined by mesoderm, instead, the mesoderm is present as scattered pouches in between the ectoderm and endoderm. Such a body cavity is called pseudocoelom and the animals possessing them are called pseudocoelomates.
