Match List-I with List-II:
| List I | List II |
| :--- | :--- |
| (a) Metamerism | (i) Coelenterata |
| (b) Canal system | (ii) Ctenophora |
| (c) Comb plates | (iii) Annelida |
| (d) Cnidoblasts | (iv) Porifera |
Choose the correct answer from the options given below:
- A(a)-(iii); (b)-(iv); (c)-(ii); (d)-(i)
- B(a)-(iv); (b)-(i); (c)-(ii); (d)-(iii)
- C(a)-(iv); (b)-(iii); (c)-(i); (d)-(ii)
- D(a)-(iii); (b)-(iv); (c)-(i); (d)-(ii)
Solution & Step-by-step Explanation
1. Metamerism (segmentation) is characteristic of Annelida → (iii).
2. Canal system is found in Porifera (Sponges) → (iv).
3. Comb plates are the locomotory organs of Ctenophora → (ii).
4. Cnidoblasts (stinging cells) are found in Coelenterata (Cnidaria) → (i).
Sequence: (a)-(iii), (b)-(iv), (c)-(ii), (d)-(i).
