A patient presents with extreme thirst (polydipsia) and excretion of large volumes of highly dilute urine (polyuria). Clinical tests show normal blood glucose levels. Which of the following is the most likely endocrine explanation for this condition?

Options:

• A: Hyposecretion of insulin by the beta cells of the pancreas.
• B: Hypersecretion of aldosterone by the adrenal cortex.
• C: Hyposecretion of Antidiuretic Hormone (ADH) by the posterior pituitary.
• D: Hypersecretion of thyroxine by the thyroid gland.
