The correct option is C Anterior part of pituitary gland
Follicle stimulating hormone (FSH) is secreted by the anterior pituitary gland. It promotes spermatogenesis in seminiferous tubules of male and follicle development in females. Thus, option D is correct. Option B is incorrect as posterior pituitary gland does not secrete any hormone; vasopressin and oxytocin are produced by hypothalamus but stored and released into the bloodstream via posterior pituitary. Gonads (testes and ovaries) serve as endocrine organs and secrete androgens and estrogen and progesterone respectively. Thus, option A is incorrect. Thyroxine and triiodothyronine are thyroid hormones which target all tissues and stimulates metabolic rate, growth, and development. Hence, option C is incorrect. Thus, the correct answer is D.
