(a)-(iv), (b)-(i), (c)-(ii), (d)-(iii)
Metamerism is commonly seen in the members of phylum Annelida where the body is externally and internally divided into segments with a serial repetition of atleast some organs. Water canal system is present in the members of phylum Porifera. The body of ctenophores bears 8 external rows of ciliated comb plates which help in locomotion. Cnidoblasts or cnidocytes are characteristic feature of cnidarians (coelenterata).
This question aligns with the NEET BIOLOGY syllabus, specifically targeting concepts from General. Mastering this topic is crucial for scoring well in the upcoming medical entrance examinations.
