The correct option is B Adrenal medulla
Thyroid stimulating hormone (TSH) and adrenocorticotropic hormone (ACTH) are secreted by an anterior pituitary gland that targets thyroid gland and adrenal cortex respectively to produce their hormones. Interstitial cell-stimulating hormone (ICSH) promotes secretion of androgens from testes. Secretory activity of adrenal medulla is under control of sympathetic nerve fibers of the nervous system. Thus, the correct option is C.
