Correct answer
C. ( a ) − ( iii ) ; ( b ) − ( iv ) ; ( c ) − ( ii ) ; ( d ) − ( i )
Step-by-step solution
Metamerism is a characteristic feature of the annelids which signifies the presence of body segments. A water canal system is present in poriferans to aid digestion, excretion and respiration. Comb plates allow the ctenophores to locomote and the cnidoblasts are the structure of offence and defence in Coelenterata.
