Answer : c
Hints & Solutions
(c) Estrogens are steroid hormones secreted by growing ovarian follicles. During menstrual cycle a negative feedback prevents the secretion of estrogen. FSH stimulates maturation of Graafian follicles. LH stimulates ovulation and development of corpus luteum. In response to various types of injury, melanocyte stem cells (McSCs) located in the bulge of hair follicles can regenerate mature melanocytes for hair and skin pigmentation.
