Correct answer

D. Assertion is false but Reason is true

Step-by-step solution

Wuchereria belongs to the phylum Aschelminthes. Members of Aschelminthes are pseudocoelomates, not true coelomates. Therefore, the Assertion is false. In pseudocoelomates like Wuchereria, the body cavity is not completely lined by mesoderm. Instead, the mesoderm is present as scattered pouches in between the ectoderm and endoderm. Therefore, the Reason is true. Answer: Assertion is false but Reason is true
