The correct answer is (c) FSH and LH
During the menstrual cycle, FSH and LH are secreted by the pituitary gland and play essential roles in the regulation of ovarian function and the development of follicles.
FSH stimulates the growth and maturation of ovarian follicles, which contain the eggs. As the follicles grow, they produce estrogen. Estrogen, in turn, stimulates the thickening of the uterine lining (endometrium) in preparation for potential implantation of a fertilized egg.
LH surge triggers ovulation, which is the release of a mature egg from the ovary. After ovulation, the ruptured follicle in the ovary forms a structure called the corpus luteum, which produces progesterone.
Therefore, while estrogen and progesterone are important hormones in the menstrual cycle, the primary hormones directly involved in regulating the cycle are FSH and LH.
