His low urine specific gravity combined with excessive thirst and urination indicates diabetes insipidus, which can be central (defect in the posterior pituitary production of ADH) or nephrogenic (kidney nonresponsive to ADH). (FA2020 p338)
Seeing as it asks us to ID the endocrine organ (and he does not have history indicative of nephrogenic, the less common variety), this indicates central diabetes insipidus and defect in posterior pituitary ADH production.
