Which of the following nutrients does your body absolutely have to function properly? a. carbohydrates b. water c. protein d. fat ( i think it's carbohydrates or protein)

I think the answer to this is idk i am crossed between carbohydrates or protein but im also thinking water because we need water in our body or else our bodies will dry out and not function property. If we drink water we can prevent our bodies from drying out and it will be able to function property.

False would be the correct answer
