Question: 160. Consider the following statements:
A. Annelids are true coelomates
B. Poriferans are pseudocoelomates
C. Aschelminthes are acoelomates
D. Platyhelminthes are pseudocoelomates
Choose the correct answer from the options given below :
(1) B only
(2) A only
(3) C only
(4) D only
Answer: Option (2)
Explanation:
Annelids possess a true coelom that is completely lined by mesoderm, so statement A is correct.
Poriferans do not have a true tissue organization and lack a coelom, so they are neither true coelomates nor pseudocoelomates, making statement B incorrect.
Aschelminthes are pseudocoelomates, not acoelomates, so statement C is incorrect.
Platyhelminthes are acoelomates and do not possess a body cavity, so statement D is incorrect.
Therefore, only statement A is correct, and the correct answer is option (2).
