A
Antidiuretic hormone (ADH)
B

C

D

Verified step by step guidance1
Identify the hormones listed and their primary functions: Antidiuretic hormone (ADH) regulates water balance, Prolactin stimulates milk production, Follicle-stimulating hormone (FSH) is involved in reproductive processes like egg and sperm development.
Recall that the posterior pituitary gland releases two main hormones: Antidiuretic hormone (ADH) and Oxytocin.
Understand that Oxytocin is the hormone responsible for stimulating uterine contractions during labor, facilitating childbirth.
Recognize that the question asks specifically for the hormone released from the posterior pituitary that stimulates uterine contractions, which matches Oxytocin's role.
Conclude that among the options, Oxytocin is the correct hormone linked to uterine contractions during labor.
