Solution
The correct option is C LH
Changes in the ovary and the uterus during the menstrual cycle are induced by changes in the levels of pituitary and ovarian hormones. The secretion of gonadotropins (LH and FSH) increases gradually during the follicular phase, and stimulates follicular development as well as secretion of estrogens by the growing follicles. Both LH and FSH attain a peak level in the middle of the cycle (about the 14th day). Rapid secretion of Luteinising Hormone (LH) leading to its maximum level during mid-cycle called LH surge induces rupture of Graafian follicle and thereby, the release of ovum (ovulation).
