D) Pedigree
Chorionic Villus Sampling
A prenatal diagnostic test that involves collecting a small sample of the placental tissue, known as the chorionic villi, to test for genetic abnormalities.
Amniocentesis
A medical procedure used in prenatal diagnosis, where a small amount of amniotic fluid is extracted from the amniotic sac surrounding a developing fetus.
Karyotype
An individual's complete set of chromosomes, visually represented in a photograph or diagram which displays the chromosomes arranged by size and number.

Final Answer :
C
Explanation :
Chorionic villus sampling (CVS) is a prenatal test in which a sample of placental tissue is removed and analyzed to detect chromosomal abnormalities and genetic disorders. This is done by inserting a needle or tube through the mother's cervix or abdomen to obtain a small sample of the chorionic villi, which are finger-like projections on the placenta that contain fetal cells. Amniocentesis is a different type of prenatal test that involves removing a sample of amniotic fluid, while karyotyping is a laboratory technique used to analyze chromosomes. Pedigree is a graphical representation of inherited traits in a family but is not a method of obtaining placental tissue samples.
