Solution

The correct option is A Hypothalamus
Thirst is not brains only response to dehydration. When the body gets low on water, the hypothalamus increases the synthesis of an antidiuretic hormone called vasopressin, which is selected by the pituitary gland and travels to the kidneys.
So, the correct option is 'hypothalamus'.
