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

**Step-by-Step Solution:**

1. **Understanding Infertility**:
- Infertility is defined as the inability to conceive or produce children after 2 years of unprotected sexual cohabitation. This means that if a couple has been trying to conceive without using any birth control methods for two years and has not succeeded, they are considered infertile.

2. **Understanding In Vitro Fertilization (IVF)**:
- In Vitro Fertilization (IVF) is a medical procedure where fertilization occurs outside of the female body. This involves taking an egg and sperm and allowing them to fertilize in a laboratory setting.

3. **Embryo Transfer**:
- After fertilization, the resulting embryo is then transferred into the female's uterus. This process is commonly referred to as the "Test Tube Baby" program because the fertilization occurs in a test tube or a similar laboratory environment.

4. **Evaluating the Assertion and Reason**:
- The assertion states that infertility is the inability to conceive after 2 years of unprotected sexual cohabitation, which is correct.
- The reason states that IVF followed by embryo transfer is known as the "Test Tube Baby" program, which is also correct.
- However, while both statements are true, the reason does not explain why the assertion is true. The assertion describes a condition (infertility), while the reason describes a method (IVF) that can be used to address that condition.

5. **Conclusion**:
- Since both the assertion and reason are true, but the reason does not provide a proper explanation for the assertion, the correct answer is that both statements are true, but the reason is not a correct explanation of the assertion.

**Final Answer**: Both assertion and reason are true, but the reason is not a correct explanation of the assertion (Option 2).
