Assertion : In test-tube baby program, ova from wife/donor (female) and sperms from husband/donor (male) are collected and are induced to form zygote under simulated conditions in laboratory.
Reason : Embryos with more than 8 blastomeres are then transferred to fallopian tube (ZIFT) to complete its further development.

Options

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

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 in the test-tube baby program, ova from the wife or a donor and sperm from the husband or a donor are collected and induced to form a zygote under simulated conditions in a laboratory.
- This process is known as In Vitro Fertilization (IVF). It is indeed true that the ova and sperm are collected and fertilization occurs in a controlled laboratory environment.

2. **Understanding the Reason**:
- The reason given is that embryos with more than 8 blastomeres are transferred to the fallopian tube (ZIFT) to complete their further development.
- This statement is incorrect. In reality, embryos with up to 8 blastomeres are transferred to the fallopian tube (ZIFT), while embryos with more than 8 blastomeres are typically transferred to the uterus (IUT).

3. **Analyzing the Relationship**:
- The assertion is true as it accurately describes the IVF process.
- The reason is false because it misstates the conditions under which embryos are transferred.

4. **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 correct option is **3**: Assertion is true but reason is false.
