Answer 1

Answer: (B)

A only

Answer 2

- A. Annelids are true coelomates– True. Annelids have a true coelom, which is a body cavity completely lined by mesoderm.

- B. Poriferans are pseudocoelomates- False. Poriferans (sponges) are acoelomates, meaning they lack a true body cavity.

- C. Aschelminthes are acoelomates– False. Aschelminthes are pseudocoelomates, meaning they have a body cavity that is not fully lined by mesoderm.

- D. Platyhelminthes are pseudocoelomates– False. Platyhelminthes (flatworms) are acoelomates, meaning they lack a body cavity.

Thus, the correct answer is A only, so the correct answer is (1).
