(b)	Canal system	(II)	Ctenophora
(c)	Comb plates	(III)	Annelida
(d)	Cnidoblasts	(IV)	Porifera

Choose the correct answer from the options given below.

• A. (IV) (I) (II) (III)
• B. (IV) (III) (I) (II)
• C. (IV) (III) (I) (II)

(b) (IV) (III) (I) (II) - This option matches Canal system with Annelida (incorrect). 

(c) (III) (IV) (I) (II) - This option matches Comb plates with Ctenophora (correct). 

(d) (III) (IV) (II) (I) - This option matches Cnidoblasts with Coelenterata, which is accurate.

so, The correct option is (D), which correctly matches the items in List - I with their respective phyla in List - II:

(a) (III) (Annelida) (b) (IV) (Porifera) (c) (II) (Ctenophora) (d) (I) (Coelenterata or Cnidaria)
