B It is a false body cavity, partially lined by mesoderm.
Correct Answer
C There is no body cavity present.
D The body cavity is reduced and filled with hemolymph.
Correct Answer

Option B is the correct answer.

Detailed Explanation

The 'Phylum Nematoda (Roundworms)' section states, 'Body cavity: Pseudocoelomate (false body cavity, not fully lined by mesoderm).' This definition is reinforced in the 'Corrections & Clarifications' section.
