Which one is correct pair ?

Options

A. Echinodermate- Cuttle Fish
B. Arthropoda - Silver Fish
C. Mollusca- Star Fish
D. Pisces- Jelly Fish.

Answer

To solve the question "Which one is correct pair?" we need to analyze the options given and identify the correct classification of the organisms mentioned.

### Step-by-Step Solution:

1. **Identify the Organisms in Each Option:**
- Option A: Echinodermate (Cuttlefish), Arthropod (Silverfish), Mollusk (Starfish), Piscis (Jellyfish)
- Option B: Arthropod (Silverfish), Echinodermata (Starfish), Mollusca (Cuttlefish), Cnidaria (Jellyfish)

2. **Classify Each Organism:**
- **Cuttlefish**: This organism is a mollusk, specifically a cephalopod, so it belongs to the phylum Mollusca.
- **Silverfish**: This is a small, primitive, wingless insect that belongs to the order Zygentoma, which is classified under the phylum Arthropoda.
- **Starfish**: This organism is a marine invertebrate that belongs to the phylum Echinodermata.
- **Jellyfish**: This organism belongs to the phylum Cnidaria.

3. **Analyze the Options:**
- In Option A, the pairings are incorrect:
- Cuttlefish (Mollusca) is incorrectly paired as Echinodermate.
- Silverfish (Arthropoda) is correctly paired.
- Starfish (Echinodermata) is incorrectly paired as Mollusk.
- Jellyfish (Cnidaria) is incorrectly paired as Piscis.
- In Option B, the pairings are:
- Silverfish (Arthropoda) is correctly paired.
- Starfish (Echinodermata) is correctly paired.
- Cuttlefish (Mollusca) is correctly paired.
- Jellyfish (Cnidaria) is correctly paired.

4. **Conclusion:**
- The correct pair is found in Option B, where Silverfish is correctly classified under Arthropoda.

### Final Answer:
The correct answer is **Option B**: Arthropod (Silverfish).
