B. estrogen
C. progesterone
D. testosterone
Solution
The answer is the first one (A): human chorionic gonadotropin.
Explanation for each option:
A. Human chorionic gonadotropin (hCG) - Correct. This hormone is produced by the placenta shortly after the embryo attaches to the uterine lining. It is the hormone detected by urine pregnancy tests to confirm pregnancy.
B. Estrogen - Incorrect. While estrogen levels do rise during pregnancy, they are not used in standard urine pregnancy tests.
C. Progesterone - Incorrect. Progesterone is important for maintaining pregnancy, but it is not the hormone detected by urine pregnancy tests.
D. Testosterone - Incorrect. Testosterone is a male sex hormone and is not relevant to pregnancy detection.
In summary, urine pregnancy kits check for the presence of human chorionic gonadotropin (hCG) to confirm pregnancy.
