The synthesis and release of thyroxine from the thyroid gland is stimulated by

The correct option is B TSH
Follicle stimulating hormone (FSH) promotes spermatogenesis in seminiferous tubules of male and follicle development in females. Option D is incorrect. LH is also gonadotropin and stimulates production of sex hormones by gonads. Hence, option A is incorrect. The thyroid stimulating hormone of anterior pituitary stimulates secretion of thyroxin by binding to the receptors of follicle of thyroid gland. Thus, option B is correct. ACTH regulates the secretion of glucocorticoids (cortisol, corticosterone, and cortisone) by adrenal cortex via a negative feedback mechanism. Thus, makes option C incorrect. Hence, the correct answer is B.
