Solution

The correct option is A Luteinizing hormone
During menstrual cycle in human females, changes in the ovary and the uterus 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 cycle (about 14th day). The LH surge triggers the ovulation process.
Thus, the correct answer is option A.
