Final Answer :
B
Explanation :
Milk production in breasts is triggered by the hormone prolactin, which is released by the anterior pituitary gland. Option A is incorrect because prolactin is not released by the hypothalamus, but it does regulate prolactin release from the anterior pituitary. Options C and D are incorrect because oxytocin is responsible for milk letdown (the release of milk from the breast during breastfeeding), but not milk production. Option E is incorrect because estrogen does not directly trigger milk production.
