The question asks which of the following hormone–gland pairings is INCORRECT.
Option a: Calcitonin - thyroid gland. Calcitonin is a hormone produced by the parafollicular C cells of the thyroid gland, so this pairing is correct.
Option b: Androgen - testes. Androgens (primarily testosterone) are produced by the testes, so this pairing is correct.
Option c: Aldoesterone - adrenal glands. The hormone is aldosterone, which is produced by the adrenal cortex within the adrenal glands. This pairing is conceptually correct, though note the usual spelling is aldosterone; the gland reference is acceptable, so this is correct.
Option d: Thyrotropin releasing hormone – anterior pituitary gland. Thyrotropin-releasing hormone (TRH) is produced by the hypothalamus and stimulates the anterior pituitary to release thyroid-stimulating hormone (TSH). The hormone–gland pairing implies TRH is produced by or acts on the anterior pituitary, which is not accurate—the correct association is hypothalamus (produces TRH) to anterior pituitary (stimulated). Therefore, this pairing is incorrect.
Option e: Oxytocin – posterior pituitary gland. Oxytocin is synthesized in the hypothalamus and stored/released from the posterior pituitary; pairing it with the posterior pituitary gland is correct.
Thus, the only incorrect pairing is option d, Thyrotropin releasing hormone – anterior pituitary gland, because TRH originates in the hypothalamus and acts on the anterior pituitary rather than being produced by it.
