Options

A. Suckers and mouth
B. Claws on digits
C. Adhesive lamellar pads on digits
D. Sticky ventral side of the digits

Answer

To solve the question "A house lizard can climb a smooth wall due to the presence of," we can follow these steps:

### Step 1: Understand the Question
The question is asking about the specific adaptations that allow a house lizard to climb smooth surfaces, such as walls.

**Hint:** Think about the physical features of lizards that help them adhere to surfaces.

### Step 2: Analyze the Options
We have several options to consider:
1. Sucker and mouth
2. Claws and digits
3. Adhesive lamellar pads on digits
4. Sticky ventral side of the digit

**Hint:** Recall the specific adaptations of lizards compared to other animals.

### Step 3: Evaluate Each Option
- **Option 1: Sucker and mouth** - This is characteristic of octopuses, not lizards. Therefore, this option is incorrect.

- **Option 2: Claws and digits** - While lizards do have claws, this adaptation is not specifically for climbing smooth surfaces. This option is also incorrect.

- **Option 3: Adhesive lamellar pads on digits** - Lizards have specialized structures on their toes called adhesive lamellae, which allow them to stick to and climb smooth surfaces. This is the correct answer.

- **Option 4: Sticky ventral side of the digit** - This is not a feature of lizards. Therefore, this option is incorrect.

**Hint:** Focus on the unique adaptations that specifically enable climbing.

### Step 4: Conclusion
Based on the evaluation, the correct answer is **Adhesive lamellar pads on digits**, as they are the structures that enable house lizards to climb smooth walls effectively.

**Final Answer:** The house lizard can climb a smooth wall due to the presence of adhesive lamellar pads on its digits.
