Step-by-step solution

During the follicular phase, the growing ovarian follicles secrete estrogens (A matches IV). The rapid secretion of LH leading to its maximum level during the mid-cycle (LH surge) induces the rupture of the Graafian follicle (B matches III). After ovulation, the ruptured follicle transforms into the corpus luteum, which secretes large amounts of progesterone (C matches I). In the absence of fertilisation, the corpus luteum degenerates, which causes the disintegration of the endometrium leading to menstruation (D ma
