Answer: The correct answer is-

A. organs, but no true body cavity.

Based on the presence of body cavity ( also called coelom), multicellular animals can be classified as acoelomates ( no true body cavity), coelomates ( having true body cavity), pseudocoelomates ( false body cavity).

Roundworms are pseudocoelomic. This means that organs are present but the body cavity is not lined by mesodermal epithelium.

Body cavity is present between the external wall of body and the intestine and it baths the different body organs.

Thus, option A) is the right answer.

Answer:

Option A

Explanation:

All bilateral  organisms have coelomates (cavity). However a Pseudocoelomate organism have a false cavity. By false cavity, we mean that there is a body cavity which is filled with fluid and all internal organs bathe in it including alimentary canal system , reproductive system etc. Unlike a coelom, Pseudocoelomate organism do not have body cavity  completely lined with mesodermal cells.

hence, option A is correct
