The permissible use of the technique amniocentesis is for :

Options

A. detecting sex of the unborn foetus
B. artifical insemination
C. transferof embryo into the uterus of a surrogate mother
D. detecting any genetic abnormality

Answer

### Step-by-Step Solution

1. **Understanding Amniocentesis**:
- Amniocentesis is a medical procedure used to obtain amniotic fluid from the uterus. This fluid surrounds and protects the fetus during pregnancy and contains cells that can be analyzed for various purposes.

2. **Identifying the Purpose of Amniocentesis**:
- The primary use of amniocentesis is to test for genetic abnormalities in the fetus. This includes conditions like Down syndrome and other genetic disorders.

3. **Evaluating the Options**:
- **Option A: Detecting sex of the unborn fetus**: While amniocentesis can determine the sex of the fetus, this use is often not permissible in many countries, including India, due to ethical concerns about female foeticide.
- **Option B: Artificial insemination**: This is a completely different procedure that involves the introduction of sperm into the female reproductive system and is not related to amniocentesis.
- **Option C: Transfer of embryo into the uterus of surrogate mother**: This refers to assisted reproductive technology (ART) and is also unrelated to amniocentesis.
- **Option D: Detecting genetic abnormalities**: This is a legitimate and permissible use of amniocentesis, as it allows for early detection of genetic disorders.

4. **Conclusion**:
- After evaluating all the options, the correct and permissible use of amniocentesis is for **detecting genetic abnormalities**.

### Final Answer:
**The permissible use of the technique amniocentesis is for detecting any genetic abnormalities. (Option D)**
