Answer (2)

Roundworms differ from flatworms primarily in having a pseudocoelom, which is a body cavity that provides space for organs and allows for more sophisticated body systems. Flatworms, on the other hand, lack a true body cavity and circulatory system. Therefore, the correct option is B. Pseudocoelom.
