Answer

To solve the question, we need to evaluate each statement regarding Intrauterine Devices (IUDs) and determine if they are true or false.

### Step-by-Step Solution:

1. **Evaluate Statement 1**: "An IUD can be inserted by a lady herself into the uterus through her vagina."
- **Analysis**: This statement is false. IUDs must be inserted by a healthcare professional, not by the individual herself.
- **Conclusion**: Statement 1 is **False**.

2. **Evaluate Statement 2**: "IUDs increase phagocytosis of sperms in the fallopian tube."
- **Analysis**: This statement is also false. IUDs do not increase phagocytosis of sperm; instead, they create a hostile environment for sperm.
- **Conclusion**: Statement 2 is **False**.

3. **Evaluate Statement 3**: "Copper ions suppress sperm motility and fertilizing capacity."
- **Analysis**: This statement is true. Copper ions released from copper IUDs do suppress sperm motility and their ability to fertilize an egg.
- **Conclusion**: Statement 3 is **True**.

4. **Evaluate Statement 4**: "Hormone releasing IUDs prevent ovulation."
- **Analysis**: This statement is true. Hormone-releasing IUDs (like Mirena) release hormones that can prevent ovulation.
- **Conclusion**: Statement 4 is **True**.

### Final Evaluation:
Based on the evaluations:
- Statement 1: False
- Statement 2: False
- Statement 3: True
- Statement 4: True

The correct option that matches these evaluations is **(b) 1 - False, 2 - False, 3 - True, 4 - True**.
