Step-by-step solution
During the menstrual cycle, the rapid secretion of LH leading to its maximum level during the mid-cycle is called LH surge, which induces the rupture of the Graafian follicle (A matches IV). After ovulation, the remaining parts of the ruptured Graafian follicle transform into a temporary endocrine structure called the corpus luteum (B matches III). The corpus luteum secretes large amounts of progesterone, which is essential for the maintenance of the endometrium for a possible pregnancy (C matches II). In the absen
