Options

A.
B.
C.
D.

Answer

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

### Step-by-Step Solution:

1. **Identify the First Pairing:**
- **Example of Vertebrate:** Calutene (Garden Lizard)
- **Character:** Epidermal scales on the body
- **Class:** Reptilia
- **Analysis:** The garden lizard (Calutene) indeed has epidermal scales, which are also known as scutes. It belongs to the class Reptilia, which is correct. Therefore, this pairing is correct.

2. **Identify the Second Pairing:**
- **Example of Vertebrate:** Neophron (Vulture)
- **Character:** Skin usually without oil glands
- **Class:** Aves (Birds)
- **Analysis:** The vulture (Neophron) does have skin that is generally without oil glands, but it is important to note that birds have preen glands near the tail that help in feather maintenance. However, the statement regarding the absence of oil glands in the skin is generally correct. Thus, this pairing is also correct.

3. **Identify the Third Pairing:**
- **Example of Vertebrate:** Pristis (Sawfish)
- **Character:** Streamline body
- **Class:** Chondrichthyes (Cartilaginous fish)
- **Analysis:** The sawfish (Pristis) does have a streamlined body, but it belongs to the class Chondrichthyes, not Osteichthyes (which refers to bony fish). Therefore, this pairing is incorrect as it states the wrong class for Pristis.

4. **Identify the Fourth Pairing:**
- **Example of Vertebrate:** Ichthyophis (Limbless Worm)
- **Character:** Cloaca
- **Class:** Amphibia
- **Analysis:** Ichthyophis is indeed an amphibian and has a cloaca, which is a common feature in amphibians. Therefore, this pairing is correct.

### Conclusion:
After analyzing all the pairings, the incorrect pairing is the third option: Pristis (Sawfish) with the class listed as Osteichthyes instead of Chondrichthyes.

**Final Answer:** The incorrect pairing is the third option.
