Released from the pituitary, this hormone stimulates uterine contractions during birth.
A
Prolactin
B
Steroids
C
Estrogen
D
Oxytocin
Explanation: 

Detailed explanation-1: -During labor, when the fetus’s body (usually head) pushes against your cervix, the nerve impulses from this stimulation travel to your brain and stimulate your pituitary gland to release oxytocin into your bloodstream. The oxytocin travels to your uterus and stimulates contractions.

Detailed explanation-2: -Your posterior pituitary’s main functions are to store and release the hormones oxytocin and vasopressin (antidiuretic hormone).

Detailed explanation-3: -Oxytocin is released in response to activation of sensory nerves during labor, breastfeeding and sexual activity. In addition oxytocin is released in response to low intensity stimulation of the skin, e.g., in response to touch, stroking, warm temperature, etc.

Detailed explanation-4: -Oxytocin stimulates powerful contractions that help to thin and open (dilate) the cervix, move the baby down and out of the birth canal, push out the placenta, and limit bleeding at the site of the placenta.
