Correct answer: D. Oxytocin
- A. Prolactin
- B. GnRH
- C. FSH

Explanation
Oxytocin is the hormone primarily responsible for stimulating contractions of the uterine muscles during labor (parturition). It is released by the posterior pituitary gland in response to various stimuli such as pressure on the cervix, uterine stretching, and emotional factors. Oxytocin stimulates rhythmic contractions of the uterine muscles, which help to push the baby through the birth canal during childbirth.
