B) Luteinizing hormone (LH)

D) Follicle-stimulating hormone (FSH)
B
Feedback:
When the circulating estrogen level rises high enough, it stimulates a massive release of LH from the anterior pituitary causing one of the developing follicles to burst and release the ovum with its stored hormones into the system. ACTH targets the adrenal corticosteroid hormone, which helps prepare the body for the "fight or flight" response. Prolactin is responsible for milk production and FSH in combination with LH stimulate follicles on the outer surface of the uterus to grow and develop and also stimulates the release of estrogen and progesterone.
