In amniocentesis, the fluid for test is taken from
1 Foetal blood
2 Mother's blood
3 Amniotic fluid
4 Mother's body fluid
Explanation:
In amniocentesis, the fluid surrounding the foetus also known as amniotic fluid is taken for testing and analysis. This helps in ruling out the possibilities of any chromosomal defects.
