Assertion :- Surgical methods is terminal method to prevent any more pregnency.
Reason :- Surgical intervention blocks lumen of uterus there by prevent implantation.

Options

A. If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion.
B. If both Assertion & Reason are True but Reason is not a correct explanation of the Assertion.
C. If Assertion is True but the Reason is False.
D. If both Assertion & Reason are False.

Answer

To solve the 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 is a terminal method to prevent any more pregnancy."
- This means that surgical methods, such as sterilization, are irreversible and effectively prevent future pregnancies.
- Surgical methods include procedures like vasectomy in males and tubectomy in females.

2. **Understanding the Reason**:
- The reason states that "Surgical intervention blocks the lumen of the uterus thereby preventing implantation."
- This implies that the surgical method involves blocking the uterus to prevent a fertilized egg from implanting.
- However, this statement is misleading because the surgical methods (like tubectomy) do not block the uterus directly; instead, they cut the fallopian tubes, preventing the sperm from reaching the egg.

3. **Evaluating the Truth of the Assertion**:
- The assertion is true. Surgical methods are indeed terminal and prevent further pregnancies.

4. **Evaluating the Truth of the Reason**:
- The reason is false. While surgical methods prevent pregnancy, they do not block the lumen of the uterus. Instead, they prevent fertilization by cutting the fallopian tubes.

5. **Conclusion**:
- Since the assertion is true and the reason is false, the correct answer is that the assertion is true, but the reason is false.

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