Solution
The correct option is B Human chorionic gonadotropin
The process of implantation leads to the formation of placenta. Following implantation, hCG is secreted by syncitiotrophoblasts of placenta from the implanting conceptus during week 2.
The various hormones produced by placenta are human chorionic gonadotropin (hCG), human placental lactogen (hPL), relaxin, and a certain quantity of progesterone and estrogen. hPL is also known as human chorionic somatomammotropin. It promotes growth of most of the foetal tissues.
For attempting a pregnancy test, the kit contains a few strips. The strips contain antibodies that help detect the presence of hCG in urine. A positive result (denoted by 2 lines) indicates pregnancy. A negative result (denoted by a single line), shows the absence of pregnancy.
