Solution

The correct option is A LH
LH (luteinizing hormone) is released by anterior lobe of pituitary gland. It causes ovulation, secretion of estrogen from mature ovarian follicle and progesterone from corpus luteum. FSH stimulates sperm formation inl the male and growth of ovarian follicles in the female. Progesterone suspends ovulation dugring pregnancy, fixes the foetus to the uterine wall, forms placenta and controls the development of the foetus in the uterus. Estradiol is the major estrogen in humans.
