Solution
The correct option is A Kidney The ingenious rodents also have specialized kidneys with extra microscopic tubules to extract most of the water from their urine and return it to the blood stream. Much of the moisture that would be exhaled in breathing is recaptured in the nasal cavities by specialized organs. If that is not sufficient, Kangaroo rats and some other desert rodents, actually manufacture their water metabolically from the digestion of dry seeds.
