Which of the following is a mismatch pair

Options

A. Scales- Reptilia
B. Comb plates - Mollusca
C. Chanocytes - Proifera
D. Parapodia - Annelida.

Answer

To determine which of the following is a mismatch pair, we need to analyze each option provided in the question.

### Step-by-Step Solution:

1. **Identify the options**: The question likely provides several pairs of organisms and their characteristics. We need to examine each pair to see if the characteristic is correctly associated with the organism.

2. **Examine the first option**:
- **Scales and Reptiles**: Reptiles are known for having scales. Therefore, this pair is correct and not a mismatch.

3. **Examine the second option**:
- **Chromatophores and Mollusca**: Chromatophores are pigment-containing cells that are typically found in certain animals, including cephalopods (like octopuses) within the Mollusca phylum. However, not all mollusks possess chromatophores, particularly the bivalves. This indicates a potential mismatch.

4. **Examine the third option**:
- **Cnidocytes and Porifera**: Cnidocytes are specialized cells found in cnidarians (like jellyfish and corals) and are not present in Porifera (sponges). This indicates another potential mismatch.

5. **Examine the fourth option**:
- **Parapodia and Annelida**: Parapodia are indeed present in certain annelids (segmented worms) and are used for locomotion. This pair is correct.

6. **Conclusion**:
- The mismatched pair is **Chromatophores in Mollusca**, as chromatophores are not universally present in all mollusks. Therefore, the answer to the question is that the mismatch is between chromatophores and mollusca.

### Final Answer:
The mismatch pair is **Chromatophores and Mollusca**.
