Explanation

To solve the matching question between Column A and Column B, we will analyze each phylum in Column A and identify the correct characteristic from Column B.

### Step-by-Step Solution:

1. **Identify the first item in Column A: Porifera**
- The characteristic associated with Porifera is the **Canal system**. This system aids in respiration, nutrition, excretion, and fertilization.
- **Match:** A → i (Canal system)

2. **Identify the second item in Column A: Aschelminthes**
- The characteristic associated with Aschelminthes is the **Muscular pharynx**. This structure is important for digestion.
- **Match:** B → iii (Muscular pharynx)

3. **Identify the third item in Column A: Annelida**
- The characteristic associated with Annelida is **Metameres**. Annelids exhibit metamerization, which is the external and internal division of their body.
- **Match:** C → v (Metameres)

4. **Identify the fourth item in Column A: Arthropoda**
- The characteristic associated with Arthropoda is **Jointed appendages**. This is a defining feature of arthropods.
- **Match:** D → iv (Jointed appendages)

5. **Identify the fifth item in Column A: Echinodermata**
- The characteristic associated with Echinodermata is the **Water-vascular system**. This system is unique to echinoderms and is used for locomotion and feeding.
- **Match:** E → ii (Water-vascular system)

### Final Matches:
- A → i (Canal system)
- B → iii (Muscular pharynx)
- C → v (Metameres)
- D → iv (Jointed appendages)
- E → ii (Water-vascular system)

### Summary of Matches:
- A - i
- B - iii
- C - v
- D - iv
- E - ii

### Correct Option:
The correct option based on the matches is:
- A → i
- B → iii
- C → v
- D → iv
- E → ii
