The correct option is B ACTH
Adrenocorticotropic hormone (ACTH), also called corticotropin or adrenocorticotropin is formed in the pituitary gland that regulates the activity of the outer region (cortex) of the adrenal glands. ACTH acts in those areas of the adrenal cortex in which the glucocorticoid hormone cortisol and corticosterone are formed. The secretion of ACTH by the pituitary itself isbregulated by another polypeptide, corticotropin-releasing hormone (CRH), which is discharged from the hypothalamus in the brain in response to impulses transmitted by the nervous system.
