- Match: **(a) Dentalium → (iv) Tusk shell**

2. **Identify Ophiura**:
- Ophiura is a type of brittle star.
- Match: **(b) Ophiura → (i) Brittlestar**

3. **Identify Antedon**:
- Antedon is known as Sea lily.
- Match: **(c) Antedon → (v) Sea lily**

4. **Identify Echinus**:

- Match: **(d) Echinus → (iii) Sea Urchin**

5. **Identify Sepia**:
- Sepia is commonly known as Cuttlefish.
- Match: **(e) Sepia → (ii) Cuttle fish**

### Final Matches:
- (a) Dentalium → (iv) Tusk shell
- (b) Ophiura → (i) Brittlestar
- (c) Antedon → (v) Sea lily
- (d) Echinus → (iii) Sea Urchin
- (e) Sepia → (ii) Cuttle fish

### Conclusion:
The correct option that matches all the pairs is the second option:
- A matches with 4th, B matches with 1st, C matches with 5th, D matches with 3rd, and E matches with 2nd.
