B.
C.
D.

Answer

To solve the question of selecting the incorrect pairing, we will analyze each of the provided options step by step.

### Step-by-Step Solution:

1. **Option 1: Calotes - Reptiles**
- **Analysis**: Calotes, commonly known as the garden lizard, belongs to the class Reptilia. Reptiles are characterized by their scaly skin, which is made up of epidermis and scales (scutes). This pairing is correct.

2. **Option 2: Neophron - Aves**
- **Analysis**: Neophron refers to vultures, which are indeed classified under Aves (birds). Birds typically have dry skin, and while some may have oil glands, they are not universally present. This statement is also correct.

3. **Option 3: Pristis - Austic Thys (Bony Fishes)**
- **Analysis**: Pristis refers to sawfish, which are classified as Chondrichthyes (cartilaginous fishes), not Osteichthyes (bony fishes). Therefore, this pairing is incorrect because it misclassifies sawfish as bony fishes.

4. **Option 4: Icthyophis - Amphibians**
- **Analysis**: Icthyophis is indeed an amphibian, also known as the blind worm. It possesses a cloaca, which is a characteristic feature of amphibians. This pairing is correct.

### Conclusion:
The incorrect pairing is **Option 3: Pristis - Austic Thys (Bony Fishes)**, as Pristis (sawfish) is not a bony fish but a cartilaginous fish.
