Final Answer :
B

The stimulation of stretch receptors in the cervix by the pressure of the fetus triggers afferent neurons to send signals to the maternal hypothalamus, which in turn results in increased oxytocin production. Oxytocin is a hormone that plays a crucial role in labor by stimulating uterine contractions.
