Which prenatal screening method can help detect congenital deformities before birth?

• A. Amniocentesis
• B. Antibiotics
• C. Vaccination
• D. Physiotherapy

Answer: (A)

Prenatal detection of fetal anomalies relies on analyzing fetal material to reveal genetic or developmental issues before birth. Amniocentesis collects a small amount of amniotic fluid under ultrasound guidance, and the fetal cells and biochemistry in that fluid are tested for chromosomal abnormalities and certain birth defects. This direct examination of fetal material is what enables identifying congenital deformities before birth, guiding planning and care. Antibiotics, vaccination, and physiotherapy do not assess the fetus in utero or diagnose fetal conditions; they involve treating infection, preventing disease, or assisting physical function, respectively. Therefore, amniocentesis is the method that can reveal congenital deformities before birth.
