Amniocentesis = a prenatal diagnostic technique in which a small amount of amniotic fluid is withdrawn from the womb and analyzed.

Uses of amniocentesis:

•  Detect genetic disorders / chromosomal abnormalities (Down syndrome, sickle cell anemia, thalassemia, etc.).
• Detect certain metabolic disorders.
• Sometimes used to assess fetal lung maturity / survivability.
• It is not legally allowed for determining sex of the foetus (banned in India under PCPNDT Act).
•  It is not related to immunization at all.

 Options:

(A) Sex of the foetus →  Illegal, not correct.

(B) Presence of genetic disorders → Correct.

(C) Massive child immunization →  Not related.

(D) Survivability of the fetus → Can be assessed (e.g., lung maturity).

Correct Answer: (B) and (D) only
