The hypothalamus does indeed contain an osmoregulatory center responsible for regulating water balance in the body. This osmoregulatory function is primarily carried out through the secretion of antidiuretic hormone (ADH), also known as vasopressin, which is produced in the supraoptic nuclei of the hypothalamus. ADH plays a crucial role in regulating water reabsorption in the kidneys, thereby controlling the concentration of water in the body. The Reason provided correctly explains why the hypothalamus is considered an osmoregulatory center. Hence, the correct answer is option 1 which states both the Assertion and Reason are true, and the Reason is a correct explanation of the Assertion.
