Quizplus · Accepted Answer

Oxytocin is the hormone that is responsible for inducing labor by stimulating contractions in the uterus. It is released by the mother's pituitary gland in response to the increasing levels of estrogen in the body. High enough concentration of oxytocin triggers the periodic contractions of the mother's uterus, leading to labor. Therefore, option A is the correct answer. Option B, corticotropin, is not a hormone that is involved in labor induction. Option C, cortisol, is a stress hormone and is not directly related to labor induction. Option D, oxycontin, is a painkiller that is sometimes used during labor but is not a hormone involved in labor induction.
