Answer 1

Answer:

C. Peaking of progesterone

Follicular phase is an important phase to ensure the development of egg and maturation of the follicle it is contained in. It is also characterized by the thickening of uterine wall. These changes are brought about the pituitary hormones LH and FSH and the ovarian hormone estrogen. Progesterone is required for egg release and it peaks during the luteal phase.
