• E. 1-c-ii, 2-a-v, 3-d-iv, 4-b-i, 5-e-iii.

Answer 1

The correct option is C 1-c-ii, 2-d-i, 3-e-iii, 4-b-v, 5-a-iv

(1) Cnidocytes cells present in phylum Cnidaria for offence and defence. Pennatula belongs to class Anthozoa of phylum Cnidaria.

(2) Statocyst cells present in phylum Arthropoda for balancing. Locusta belongs to class Insecta of phylum Arthropoda.

(3) The radula is a rasping organ in the buccal cavity of phylum Mollusca for feeding. Pila belongs to the class Gastropoda of phylum Mollusca.

(4) Flame cells present in phylum Platyhelminthes for osmoregulation and excretion. Fasciola belongs to class trematode of phylum Platyhelminthes.

(5) Comb plates is a special ciliated tract in phylum Ctenophora for ciliary locomotion. Ctenoplana belongs to phylum Ctenophora.

So, the correct answer is '1-c-ii,2-d-i,3-e-iii,4-b-v,5-a-iv'.
