B. The resultant zygote upto 8 - blastomere stage is transferred to test tube for further development into baby.
C. In vitro fertilization is followed by embroyo transfer into fallopian tube or uterus of female.
D. Both (a) and (c)

Answer

To answer the question "What is correct about the test-tube baby program?", we will analyze the statements provided regarding the test-tube baby program step by step.

### Step-by-Step Solution:

1. **Understanding the Test-Tube Baby Program**:
- The test-tube baby program, also known as in vitro fertilization (IVF), involves the fertilization of an ovum (egg) with sperm outside the female body, typically in a laboratory setting.

2. **Evaluating Statement 1**:
- **Statement**: "The fertilization of ovum with sperm occurs outside the female body in the laboratory."
- **Analysis**: This statement is correct. In the test-tube baby program, fertilization indeed occurs outside the female body.

3. **Evaluating Statement 2**:
- **Statement**: "The resultant zygote up to 8 blastoma stage is transferred to test tube for the further development into baby."
- **Analysis**: This statement is incorrect. The zygote is not transferred to a test tube for further development. Instead, after fertilization, the zygote is allowed to develop for a few days (usually up to the blastocyst stage) before being transferred to the uterus or fallopian tube.

4. **Evaluating Statement 3**:
- **Statement**: "In vitro fertilization by the embryo transfer into the fallopian tube or uterus of the female."
- **Analysis**: This statement is correct. After the embryo has developed, it is transferred into the uterus or fallopian tube for further development into a baby.

5. **Conclusion**:
- Based on the evaluation of the statements:
- Statement 1 is correct.
- Statement 2 is incorrect.
- Statement 3 is correct.
- Therefore, the correct answer regarding what is correct about the test-tube baby program is that fertilization occurs outside the female body, and the embryo is transferred into the uterus or fallopian tube for further development.

### Final Answer:
The correct statements about the test-tube baby program are:
1. Fertilization of ovum with sperm occurs outside the female body in the laboratory.
2. The embryo is transferred into the fallopian tube or uterus of the female for further development.
