Correct Answer: A
Solution :
During proliferative phase, the follicles start developing, hence, called follicular phase. Secretory phase is also called as luteal phase mainly controlled by progesterone secreted by corpus luteum. Estrogen further thickens the endometrium maintained by progesterone. Menstruation occurs due to decline in progesterone level and involves breakdown of overgrown endometrial lining.
