II. Hiding in burrows by some animals
III. Wearing of woolen clothes
IV. Thermal gaping
The above are examples of -

Options

A. Scansorial adaptation
B. Behavioural adaptation
C. Fossorial adaptation
D. Cursorial adaptation

Answer

To solve the question, we need to analyze each of the four points provided and identify what they have in common.

### Step-by-Step Solution:

1. **Identify the First Example: Basking by Desert Lizards in Sun**
- Desert lizards bask in the sun to increase their body temperature when the environment is cold. This behavior helps them maintain their internal temperature, which is crucial for their survival.

2. **Identify the Second Example: Hiding in Burrows by Some Animals**
- Some animals, like certain reptiles, hide in burrows to escape extreme temperatures. This behavior allows them to regulate their body temperature and avoid overheating or excessive cold.

3. **Identify the Third Example: Wearing of Woolen Clothes**
- Humans wear woolen clothes in winter to keep warm. This is a behavioral adaptation that helps maintain body temperature in cold weather, enhancing comfort and survival.

4. **Identify the Fourth Example: Thermal Gaping**
- Thermal gaping is a behavior observed in reptiles, such as crocodiles, where they open their mouths to cool down their brains when their body temperature rises too high. This is another form of behavioral adaptation to regulate temperature.

5. **Conclusion: Common Theme**
- All four examples illustrate various forms of behavioral adaptations that organisms employ to maintain their internal environment (homeostasis) in response to external temperature changes.

### Final Answer:
The above are examples of **behavioral adaptations**.
