Solution
The correct option is B Pseudocoelomate
If a body cavity which occupies a space between the mesoderm of the body wall and the endoderm of the gut is filled with fluid, it is called as pseudocoelom. An organism containing fluid filled cavity is called as pseudocoelomate.The body cavity of Ascaris is not covered by mesoderm on all sides. It is covered externally by muscles (mesoderm) but internally the lining of the intestine (endoderm). So, it is regarded as a pseudocoelomate. Thus, the correct answer is option A.
