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

Explanation

To answer the question regarding why sterilization techniques are often the last option for couples despite being foolproof methods of contraception with minimal side effects, we will analyze each of the provided options step by step.

### Step-by-Step Solution:

1. **Understanding Sterilization Techniques**:
- Sterilization methods, such as vasectomy in males and tubectomy in females, are surgical procedures aimed at permanently preventing pregnancy by blocking the transport of gametes.

2. **Evaluating Option (i)**:
- **It is almost irreversible**:
- This statement is true. Once a sterilization procedure is performed, reversing it is complex and not guaranteed to restore fertility. This makes it a significant consideration for couples contemplating this method.

3. **Evaluating Option (ii)**:
- **Of the misconception that it will reduce sexual urge/drive**:
- This is also true. There are common misconceptions that undergoing sterilization will negatively impact sexual desire or performance, which can deter couples from choosing this option.

4. **Evaluating Option (iii)**:
- **It is a surgical procedure**:
- This statement is correct. Being a surgical procedure, it carries inherent risks such as infections and complications, which may make couples hesitant to proceed.

5. **Evaluating Option (iv)**:
- **Of lack of sufficient facilities in many parts of the country**:
- This is true as well. In many regions, there may be inadequate healthcare infrastructure, trained personnel, or access to surgical facilities, which limits the availability of sterilization options.

6. **Conclusion**:
- All four options (i, ii, iii, and iv) are valid reasons why couples may consider sterilization as a last option despite its effectiveness. Therefore, the correct answer is that all options are correct.

### Final Answer:
All options (i, ii, iii, and iv) are correct.
