An Advantage of Chorionic Villus Sampling (Compared with Amniocentesis) Is

An advantage of chorionic villus sampling (compared with amniocentesis) is that:

A) chorionic villus sampling detects a much wider range of genetic defects than does amniocentesis.
B) chorionic villus sampling is much less expensive than is amniocentesis.
C) chorionic villus sampling is much less invasive than amniocentesis.
D) chorionic villus sampling is much easier to perform than amniocentesis.
E) chorionic villus sampling can be performed much earlier than amniocentesis.
