D. If both Assertion & Reason are False.

Answer

To solve the given question, we need to analyze both the assertion and the reason provided.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "Surgical methods are terminal methods to prevent any more pregnancies."
- This is true because surgical methods, such as tubectomy in females and vasectomy in males, are designed to permanently prevent future pregnancies.

2. **Understanding the Reason**:
- The reason states that "Surgical intervention blocks the lumen of the uterus thereby preventing implantation."
- This statement is false because surgical methods like tubectomy and vasectomy do not block the lumen of the uterus. Instead, they involve cutting and ligating the fallopian tubes (in females) or the vas deferens (in males) to prevent the sperm from reaching the egg or the egg from reaching the uterus.

3. **Conclusion**:
- Since the assertion is true and the reason is false, we conclude that the correct answer is that the assertion is true while the reason is false.

### Final Answer:
- The assertion is true, and the reason is false.
