Options

A. A-(i), B-(ii), C-(iii), D-(iv), E-(v)
B. A-(ii), B-(iii), C-(iv), D-(i), E-(v)
C. A-(iii), B-(v), C-(ii), D-(i), E-(iv)
D. A-(iii), B-(i), C-(v), D-(ii), E-(iv)

Answer

To solve the matching question between Column I and Column II, we will analyze each item in Column I and find its corresponding match in Column II based on the characteristics of the groups mentioned.

### Step-by-Step Solution:

1. **Identify Cyclostomers**:
- Cyclostomers are jawless fish, also known as Agnatha. The term "cyclo" means circular, and "stoma" means mouth, indicating they have a circular mouth.
- **Match**: A (Cyclostomers) → (iii) Agnatha.

2. **Identify Aves**:
- Aves refers to birds. Birds are characterized as tetrapods, meaning they have four limbs.
- **Match**: B (Aves) → (v) Tetrapod.

3. **Identify Tunicates**:
- Tunicates are also known as Urochordata. They possess a notochord only in their larval stage and are classified under this subphylum.
- **Match**: C (Tunicates) → (ii) Urochordata.

4. **Identify Balanoglossus**:
- Balanoglossus is an example of Hemichordata. It is known as a connecting link between chordates and non-chordates and possesses a structure called stomochord.
- **Match**: D (Balanoglossus) → (i) Hemichordata.

5. **Identify Osteichthyes**:
- Osteichthyes refers to bony fishes, which have a bony endoskeleton. This class falls under the superclass Pisces.
- **Match**: E (Osteichthyes) → (iv) Pisces.

### Final Matches:
- A → (iii) Agnatha
- B → (v) Tetrapod
- C → (ii) Urochordata
- D → (i) Hemichordata
- E → (iv) Pisces

### Conclusion:
The correct matching is:
- A - iii
- B - v
- C - ii
- D - i
- E - iv

Thus, the correct option based on the matches is **C1**.
