- Option 1: No eyelids
- Option 2: Movable eyelids
- Option 3: Immovable eyelids
- Option 4: Only nictitating membrane

2. **Analyzing the Options**:

- **Option 3: Immovable eyelids**: This indicates that snakes have eyelids that do not move.
- **Option 4: Only nictitating membrane**: This suggests that snakes possess a nictitating membrane, which is a type of eyelid found in some animals.

3. **Identifying the Correct Answer**:
