Step-by-step solution
Luteinizing Hormone (LH) reaches its peak level during the mid-cycle (LH surge), which induces the rupture of the Graafian follicle and causes ovulation (A matches with II). Follicle Stimulating Hormone (FSH) stimulates the growth and development of the primary follicles into mature follicles (B matches with IV). Estrogen, secreted by the growing follicles, stimulates the regeneration of the endometrium through proliferation, marking the proliferative phase (C matches with III). Progesterone is secreted by the corp
