What is the hormone that causes poor development of secondary sex characteristics?

The correct answer is C: Human chorionic gonadotropin (hCG)

Human chorionic gonadotropin (hCG) is a hormone produced by the placenta during pregnancy. It is responsible for maintaining the corpus luteum, which produces progesterone, which in turn helps to maintain the pregnancy. While the hormone is commonly found in pregnant individuals, it is not known to have a negative impact on the development of secondary sex characteristics.
