The answer is the third one (c): human chorionic gonadotropin.

Explanation for each option:

a. Progesterone: This hormone is important for maintaining pregnancy, but it is not the hormone detected in a pregnancy test. Pregnancy tests are designed to detect a specific hormone that is produced shortly after conception.

b. Testosterone: This is a male sex hormone and is not related to pregnancy detection. It is not present in significant amounts in females during pregnancy.

c. Human chorionic gonadotropin (hCG): This is the correct answer. hCG is a hormone produced by the placenta shortly after the embryo attaches to the uterine lining. It is the hormone detected by pregnancy tests, as its presence in urine or blood is an early indicator of pregnancy.

d. Estrogen: While estrogen levels do rise during pregnancy, it is not the hormone that pregnancy tests are designed to detect.

In summary, pregnancy tests detect the presence of human chorionic gonadotropin (hCG) to determine if a person is pregnant.
