A: Both vasectomy and tubectomy are very effective as the failure rate of such surgical appraoches is almost zero percent.
R: Reversibility is poor.

Options

A. If both Assertion & Reason are true and the reason is the correct explanation of the assertion, then mark (1).
B. If both Assertion & Reason are true but the reasons is not the correct expalanation of the assertion, then mark (2).
C. If Assertion is true statement but Reason is false, then mark (3)
D. If both Assertion and Reason are false statements, then mark (4).

Answer

To solve the assertion and reason question, we will analyze both statements step by step.

### Step 1: Understand the Assertion
**Assertion (A)**: "Both vasectomy and tubectomy are very effective as the failure rate of such surgical approaches is almost zero percent."
- **Explanation**: Vasectomy is a surgical procedure for male sterilization where the vas deferens is cut and tied, preventing sperm from mixing with semen. Tubectomy is a similar procedure for females, where the fallopian tubes are cut and tied, preventing eggs from reaching the uterus. Both procedures are considered highly effective, with failure rates close to zero.

### Step 2: Understand the Reason
**Reason (R)**: "Reversibility is poor."
- **Explanation**: Both vasectomy and tubectomy are designed to be permanent forms of birth control. While there are surgical procedures that can attempt to reverse these operations, the success rates are not guaranteed, and therefore, the reversibility of these methods is considered poor.

### Step 3: Analyze the Relationship Between A and R
- The assertion states that both procedures are effective, which is true. The reason provided explains a characteristic of these procedures, which is their poor reversibility. This poor reversibility contributes to their effectiveness as permanent methods of contraception.

### Step 4: Conclusion
- Both the assertion and reason are true. The reason provided does explain why the assertion is correct, as the poor reversibility of these methods reinforces their effectiveness in preventing pregnancy.

### Final Answer
- Both the assertion (A) and reason (R) are true, and the reason is the correct explanation of the assertion.
