the hormone that is the basis for a pregnancy test is
progesterone.
relaxin.
lh.
human chorionic gonadotropin (hcg).
human placental lactogen (hpl).

Explanation:

Pregnancy tests detect human chorionic gonadotropin (hCG). This hormone is produced by the placenta after implantation of the fertilized egg in the uterus. Levels of hCG rise significantly during early pregnancy, making it a reliable marker for pregnancy detection. Progesterone is involved in maintaining pregnancy but not the basis for the test. Relaxin helps in softening tissues for childbirth. LH (luteinizing hormone) is related to ovulation. Human placental lactogen (hPL) is involved in metabolism during pregnancy but not used in pregnancy tests.

Answer:

human chorionic gonadotropin (hCG).
