Answer:
D. Dehydration
Explanation:
This is because the sense of thirst is reduced in some individuals who are eldery because they account the thirst to some normal aging process. Similarly, young children might not always respond to their body's need. Obese and overweight people could also be preventing themselves from being properly hydrated by associating the feeling of thirst with hunger and consuming food that do not have adequate water content rather than consuing fruits and vegetables which have high water content.
