B)GWAS
C)chorionic villus sampling
D)fetal blood sampling

Accepted Answer

Chorionic villus sampling (CVS) is a prenatal screening procedure where a sample of the placenta is extracted and analyzed for genetic abnormalities. This procedure has greatly enhanced prenatal screening as it can detect chromosomal abnormalities and genetic disorders in the fetus as early as 10 weeks of pregnancy. CVS is a safe and effective alternative to amniocentesis and offers parents the option to make informed decisions about their pregnancy and the future of their child.
