The correct Answer is:
B
CVS (Chorinnic villi sampling) is a technique for detecting foetal disorders during early pregnancy. In this technique a doctor inserts a narrow, flexible tube through the mother's vagina and cervix into the uterus and withdraws chorionic villi from the placenta. The cells of chorionic villi are then examined for various disorders. It is done early, between `8^(th)` to `10^(th)` week of pregnancy when abortion is safe for woman.
