Which hormone regulates the production of milk after childbirth?
Correct answer
A
Rationale
The correct answer is Prolactin. Prolactin is the hormone responsible for regulating the production of milk after childbirth. It stimulates the mammary glands in the breasts to produce milk. Oxytocin, on the other hand, is responsible for the ejection of milk from the breasts. Estrogen and progesterone play roles in the menstrual cycle and pregnancy but are not directly involved in milk production. Therefore, choices B, C, and D are incorrect.
