Answer 1

The correct option is A About day $14$

FSH is secreted by anterior pituitary during the follicular phase (day 0 to 10) and stimulates the development of follicle. LH surge at day 14 causes rupture of Graffian follicle and release of the ovum. Day 15 to 28 constitute secretory phase marked by secretion of progesterone and estrogen from corpus luteum. Thus, the correct answer is the option A.
