Step-by-step explanation:

The correct statement about the menstrual cycle is a. Estrogen levels rise during the luteal phase of the ovarian cycle and the secretory phase of the uterine cycle. This occurs after ovulation, marking the start of the luteal phase in the ovarian cycle and the secretory phase in the uterine cycle, from about day 15 to 28 of a typical 28-day cycle. During this time, the ruptured follicle forms the corpus luteum, which produces both estrogen and progesterone. Progesterone is responsible for the regrowth of the uterine lining and the inhibition of further FSH and LH release, preventing the development of additional eggs and follicles while the levels are elevated. This process ensures the uterus is prepared for a potential fertilized egg.
