To determine the correct pairs in the question, we will analyze each option provided and identify the correct classification of the organisms mentioned.

### Step-by-Step Solution:

1. **Identify the Organisms and Their Phyla**:
- The question presents different organisms and their respective phyla. We need to check if the organism belongs to the mentioned phylum.

2. **Examine the First Pair**:
- **Malaska** and **Starfish**:
- Starfish is known scientifically as Asterias and is characterized by its spiny body and arms.
- Starfish actually belongs to the phylum **Echinodermata**, not Malaska.
- Therefore, this pair is incorrect.

3. **Examine the Second Pair**:
- **Echinodermata** and **Starfish**:
- Since we established that starfish belongs to Echinodermata, this pair is correct.

4. **Examine the Third Pair**:
- **Cuttlefish**:
- Cuttlefish is a member of the phylum **Mollusca**, not a member of the phylum mentioned in the question.
- Therefore, this pair is incorrect.

5. **Examine the Fourth Pair**:
- **Jellyfish** and **Porifera**:
- Jellyfish, scientifically known as Aurelia, actually belongs to the phylum **Cnidaria**, not Porifera.
- Therefore, this pair is also incorrect.

6. **Conclusion**:
- The only correct pair identified is **Echinodermata** and **Starfish**. Hence, option 2 is the correct answer.

### Final Answer:
The correct pair is **Echinodermata - Starfish**.
