I. Biochemical adaptation are seen in organisms living in great depth of the ocean to face crushing pressure
II. Allen's rule explains mammals living in colder climates
III. Altitude sickness is caused because of body not getting enough oxygen due to low atmospheric pressure at high altitude
IV . Deset lizards lack behavioural means to manage to their body temperature
Choose the correct option for above adaptations

Options

A. I,II and III
B. I,II and IV
C. II,III and IV
D. I,III and IV

Answer

To solve the question regarding the adaptations mentioned, we will evaluate each statement one by one to determine their correctness.

### Step-by-Step Solution:

1. **Evaluate Statement I**: "Biochemical adaptations are seen in organisms living in great depth of the ocean to face crushing pressure."
- **Analysis**: This statement is correct. Organisms that live in deep ocean environments often have biochemical adaptations that allow them to survive under extreme pressure conditions.

2. **Evaluate Statement II**: "Allen's rule explains mammals living in colder climates."
- **Analysis**: This statement is also correct. Allen's rule states that mammals in colder climates tend to have shorter limbs and ears to minimize heat loss, which is an adaptation to conserve body heat.

3. **Evaluate Statement III**: "Altitude sickness is caused because of the body not getting enough oxygen due to low atmospheric pressure at high altitude."
- **Analysis**: This statement is correct. At high altitudes, the atmospheric pressure is lower, which results in less oxygen being available for the body, leading to altitude sickness.

4. **Evaluate Statement IV**: "Desert lizards lack behavioral means to manage their body temperature."
- **Analysis**: This statement is incorrect. Desert lizards do have behavioral adaptations to manage their body temperature, such as basking in the sun to warm up or seeking shade to cool down. They lack physiological means to regulate their temperature internally.

### Conclusion:
Based on the evaluations:
- Statements I, II, and III are correct.
- Statement IV is incorrect.

Thus, the correct option includes statements 1, 2, and 3.

### Final Answer:
The correct option is: **1, 2, and 3 are correct.**
