Solution
The correct option is B Human chorionic gonadotropin
A pregnancy test is used to determine if a woman is pregnant. This is done by analysing a sample of a woman’s urine or blood for the presence of human chorionic gonadotropin (hCG). hCG is a hormone produced by the placenta and is usually only present in a woman’s body when she is pregnant. A pregnancy test is usually performed when a health professional or a woman suspects she is pregnant, or before using clinical services which may interfere with a pregnancy. Pregnancy tests are also used for other, less common reasons, such as diagnosing abnormally progressing pregnancies and gestational trophoblastic disease (molar pregnancy).
So the correct option is 'Human chorionic gonadotropin'.
