Options

A. Amniocentesis
B. Trythroblastosis
C. Angiogram
D. Clotting test

Answer

To solve the question regarding the test used for the study of genetic and metabolic defects of an unborn baby, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for a specific test that is used to identify genetic and metabolic defects in an unborn baby.

2. **Review the Options**: The options provided are:
- A) Amniocentesis
- B) Try through blastosis
- C) Angiogram
- D) Clotting test

3. **Analyze Each Option**:
- **Option A: Amniocentesis**: This is a prenatal diagnostic procedure where a sample of amniotic fluid is taken from the amniotic sac surrounding a developing fetus. It is used to test for genetic disorders and chromosomal abnormalities.
- **Option B: Try through blastosis**: This option seems to be incorrectly phrased and does not refer to a recognized medical test for genetic defects.
- **Option C: Angiogram**: This is a medical imaging technique used to visualize the inside of blood vessels and organs, primarily to check for blockages or abnormalities in blood vessels, not for genetic defects.
- **Option D: Clotting test**: This test measures the blood's ability to clot and is not related to genetic or metabolic defects in an unborn baby.

4. **Identify the Correct Answer**: Based on the analysis, **Option A: Amniocentesis** is the only test that is specifically used for studying genetic and metabolic defects of an unborn baby.

5. **Conclusion**: Therefore, the correct answer is **A) Amniocentesis**.
