**Core Concept**
Neuronal diabetes insipidus is a rare condition characterized by the deficiency of antidiuretic hormone (ADH) secretion from the hypothalamus or its release from the posterior pituitary gland. This results in an inability to regulate water balance in the body, leading to excessive thirst and polyuria.

**Why the Correct Answer is Right**
The correct answer, **Desmopressin**, is a synthetic analogue of vasopressin (ADH) that is used to treat central diabetes insipidus. It acts on the V2 receptors in the renal collecting ducts to increase water reabsorption, thereby reducing urine production and alleviating symptoms. Desmopressin is available in various formulations, including intranasal sprays, which are particularly useful for children and adults with neuronal diabetes insipidus.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not specifically address the treatment of neuronal diabetes insipidus.
**Option B:** This option is incorrect because it is not a commonly used treatment for central diabetes insipidus.
**Option C:** This option is incorrect because it is not a suitable treatment for neuronal diabetes insipidus.

**Clinical Pearl / High-Yield Fact**
Desmopressin is a long-acting analogue that can be administered intranasally, subcutaneously, or orally, making it a versatile treatment option for central diabetes insipidus.

**Correct Answer:** C. Desmopressin
