Which of the following cannot be considered as advantage of amniocentesis?

The correct option is D Determination of sex to abort female foetus
The fluid that surrounds the foetus in mothers womb is called the amniotic fluid. Amniocentesis is done in pregnant women. This technique is used to prenatal diagnosis of chromosomal and genetic defects by extracting the amniotic fluid from the amniotic sac. But, amniocentesis is frequently misused to determine the sex of the unborn child. If the foetus is found to be female, it is followed by abortion which is totally illegal. Hence, determination of sex to abort female foetus by amniocentesis is not an advatange but instead a misuse and illegal one.
